Sexual stimulation is anything that leads to sexual arousal or orgasm. This thing can be physical or of other senses, and is known as a stimulus.

Contents

Sexual stimulation is a broad term, usually understood to mean physical touching of the genitals or other body parts. The term can, however, include stimuli affecting the mind (sexual fantasy), [1] or senses other than touch sight, smell, or hearing). Sufficient physical stimulation of the genitals usually results in an orgasm. [2] [3] [4] [5] Stimulation can be by oneself (masturbation or sexual fantasy) or by a sexual partner (sexual intercourse or other sexual activity), by use of objects or tools, or by some combination of these methods. [6]

Some people practice orgasm control, whereby a person or their partner controls the level of stimulation to prolong the experience leading up to orgasm.

Physical sexual stimulation

Physical sexual stimulation consists of touching the genitals or other erogenous zones.

Masturbation, erotic massage, and manual sex are types of physical stimulation involving the genitals. This stimulation is usually from sensitive touch receptors in the skin or other erogenous zones, which detect when they're being touched. Arousal is triggered through these receptors in these body parts, [7] which cause the release of pleasure-causing chemicals (endorphins) that act as mental rewards to pursue such stimulation. Someone may become aroused by simply touching another person, though the bulbocavernosus reflex itself is only triggered when a sexual organ (penis or clitoris) is stimulated. [8]

One study found that women benefit more from pleasurable sex with a committed partner, while gender did not impact the relationship with masturbation. [9]

The purpose of sex toys is to provide pleasure and stimulation through an alternative route than just using people's bodies. They can be used by someone on their own, with partnered sex, or group sex. They can be exciting and provide new types of stimulation that the body cannot produce, such as vibrations.

Sex toys have been used as a source of sexual stimulation for thousands of years. There have been dildos found from the Palaeolithic era, [10] made of siltstone and polished to a high gloss. Dildos were also made of camel dung and coated with resin. [11] Historians are uncertain whether these have been used for religious rituals or for personal pleasure. It is known that dildos were used for fertility rituals, [12] however. The ancient Greeks created their dildos from a carved penis covered in leather or animal intestines to create a more natural feel. [12] The Romans created double-ended dildos for use with a partner. Ancient Chinese dildos were made of bronze or other metals and some were hollow allowing them to be filled with liquid to simulate an ejaculation. [13] These were used because wealthy Chinese men would often have too many wives to please. In Persia, it was thought that the blood of the hymen was unclean, and should be avoided by husbands. On the night before a woman's wedding, a local holy man would come and break her hymen with a large stone dildo, a ritual also used to confirm the virginity of the bride. [14]

Non-genital

There are many areas through which a person can be sexually stimulated, other than the genitals. For example, the nipples, thighs, lips, and neck can all provide sexual stimulation when touched.

Nipples
One study [15] administered a questionnaire about sexual activity to 301 participants and found that 81.5% of women reported that stimulating their nipples caused or enhanced sexual arousal and that 59.1% of them asked to have their nipples stimulated during sex. Furthermore, 51.7% of men reported that nipple stimulation caused sexual arousal, and 39% said that it enhanced their existing arousal. Research using [16] [17] brain-scanning technology found that stimulating nipples in women resulted in the activation of the genital area of the sensory cortex. The research suggests the sensations are genital orgasms caused by nipple stimulation, and may also be directly linked to "the genital area of the brain". [16] [17] [18] In women, one study indicated that sensation from the nipples travels to the same part of the brain as sensations from the vagina, clitoris and cervix. Nipple stimulation may trigger uterine contractions, which then produce a sensation in the genital area of the brain. [16] [17]
Thighs
In 2012, the California Institute of Technology [19] measured brain responses in heterosexual males as they were having their inner thighs touched whilst being MRI scanned. They were either watching a video of a woman touching their thigh or a man touching their thigh. They reported more sexual pleasure when they thought it was the woman touching them than the man, and this was reflected in their MRI scans with greater arousal of their somatosensory cortex. It can be therefore concluded that the thighs are an area that can cause sexual stimulation when touched.
Lips
Lips contain a huge number of nerve endings and are considered to be an erogenous zone. Women report experiencing more pleasure from the stimulation of their lips than men do (see below for sex differences in stimulation). In addition to stimulation of the lips by touching, men can be visually stimulated by looking at a woman's lips. It has also been [20] reported that men prefer women with fuller lips because they are an indicator of youth.
Neck [21]
A sample of 800 participants rated 41 different body parts on their erogenous intensity on a scale of 1–10 (10 being the most arousing). Females reported neck stimulation as being more arousing than men did.

Sex differences in erogenous zones

This table [21] shows the sex differences in erogenous zones and includes the top ten most arousing areas for both sexes. Each body part was rated out of ten for how arousing it is when touched. Apart from body parts exclusive to one gender such as the penis or clitoris, many of the erogenous zones are similar and contain many nerve endings.

Internal stimulation

The excitation-transfer theory states that existing arousal in the body can be transformed into another type of arousal. For example, sometimes people can be sexually stimulated from residual arousal arising from something such as exercise, being transformed into another type of arousal such as sexual arousal. In one study [22] participants performed some physical exercise and at different stages of recovery had to watch an erotic film and rate how aroused it made them feel. They found that participants who were still experiencing excitatory residues from the exercise rated the film as more arousing than those who had fully recovered from the exercise. This suggests that the remaining arousal from the exercise was being transformed into sexual arousal without any external stimulation.

Alternative routes

The human sexual response is a dynamic combination of cognitive, emotional, and physiological processes. Whilst the most common forms of sexual stimulation discussed are fantasy or physical stimulation of the genitals and other erogenous areas, sexual arousal may also be mediated through alternative routes such as visual, olfactory and auditory means.

Visual

Perhaps the most researched non-tactile form of sexual stimulation is visual sexual stimulation. [23] [24] [25] An apparent example is the act of voyeurism  –a practice where an individual covertly watches another undress or engage in sexual behaviour. Although seen socio-historically as an unacceptable form of 'sexual deviation', it highlights the human tendency to find sexual stimulation through purely visual routes. The multibillion-dollar porn industry is another example. A common presumption is that men respond more strongly to visual sexual stimuli than do women. This is perhaps best exemplified by the Kinsey hypothesis that men are more prone to sexual arousal from visual stimulation than are women. [26] [27] Nonetheless, both sexes can be sexually aroused through visual stimulation. In one study, visual stimulation was tested by means of an erotic video. Although significantly higher in the male group, sexual arousal was the main emotional reaction reported by both sexes. Their physiological responses to the video also showed characteristics of sexual arousal, such as increased urinary excretions of adrenaline. [28] A subsequent study investigating male arousal showed that men were able to achieve rigid erections through visual stimulation of an erotic film alone. [29]

Studies that use visual stimulation as a means for sexual stimulation find that sexual arousal is predominantly correlated with an activation in limbic and paralimbic cortex and in subcortical structures, along with a deactivation in several parts of the temporal cortex. These same areas are activated during physical sexual stimulation, highlighting how powerful visual stimulation can be as a means of sexual arousal. [30]

Olfactory

Olfactory information is critical to human sexual behavior. One study investigating olfactory sexual stimulation found that heterosexual men experience sexual arousal in response to a female perfume. Individuals rated odourant stimulation and perceived sexual arousal. They also had functional MRI scans taken during the experiment. The results showed that olfactory stimulation with women's perfume produces activation of specific brain areas associated with sexual arousal in men. [31] Another study found that homosexual men displayed similar hypothalamic activation to that of heterosexual women when smelling a testosterone derivate present in male sweat, suggesting that sexual orientation plays a role in how humans experience olfactory sexual stimulation. [32]

Evolutionary analysis of sex differences in reproductive strategies can help explain the importance of smell in sexual arousal due to its link to immunological profile and offspring viability. [33] This is because olfactory cues may be able to trigger an incest avoidance mechanism by reflecting parts of an individual's genetic equipment. In one study, males rated visual and olfactory information as being equally important for selecting a lover, while females considered olfactory information to be the single most important variable in mate choice. Additionally, when considering sexual activity, females singled out body odour from all other sensory experiences as most able to negatively affect desire. [34]

Auditory

Auditory stimulants may also serve to intensify sexual arousal and the experience of pleasure. Making sounds during sexual arousal and sexual activity is widespread among primates and humans. These include sighs, moans, strong expirations and inspirations, increased breathing rate and occasionally, at orgasm, screams of ecstasy. Many of these sounds are highly exciting to people, and act as strong reinforcers of sexual arousal, creating a powerful positive feedback effect. [35] Thus, copulatory vocalisations are likely to serve mutual sexual stimulation for mating partners. [36]

Even when not coupled with "touching", sounds can be highly sexually arousing. Commercial erotic material (mainly produced for the male market) uses such sounds extensively. As early as the 1920s and 30s, several genres of singers turned to "low moans" for erotic effect. Vaudeville Jazz singers often incorporated sex sounds into the narrative of the lyrics. Even contemporary music such as Prince's "Orgasm" or Marvin Gaye's "You Sure Love to Ball" includes sounds of the female orgasm. [37] Research has shown music to be an auditory sexual stimulant. In one mood induction study, exposure to certain music resulted in significantly greater penile tumescence and subjective sexual arousal for men. [38] In a similar experiment, women did not show significant physiological responses to certain types of music but did report higher levels of sexual arousal. [39] Further studies have looked at the connection between auditory stimulation and the experience of sexual pleasure. Whilst the highest levels of physiological and subjective arousal were found for visual stimuli, spoken-text was found to elicit sexual arousal in men, implicating sounds as a means of sexual stimulation. [40] Phone sex is one type of arousal inducer that makes use of this effect.

Mental stimulation

Sexual arousal includes feelings, attractions and desires, as well as physiological changes. [41] These can be elicited not only by physical but also mental stimulations, such as fantasy, erotic literature, dreams, role-play, and imagination.

Fantasy

Sexual fantasy is a form of mental sexual stimulation which many people engage in. [41] It is where a person imagines a sexual experience while they are awake. Fantasy has less social or safety limits than in real life situations. It gives people more freedom to experiment or think of things they could not necessarily try in real life and can be anything from imagining your spouse naked, to imagining a sexual experience with a mythical creature. Common sexual fantasies include imagining activities with a loved partner, reliving past experiences and experiences with multiple partners of the opposite gender. [41] It is also common to have fantasies about things you would not do in real life and about taboo or illegal activities, such as forcing another, or being forced by another to have sex, intercourse with a stranger and sex with a boy or girl or older partner. [41] [42]

It is useful for research because it makes differences between male and female heterosexual preferences clearer than studies of behaviour. Many sexual fantasies are shared between men and women, possibly because of cultural influence. [42] However, there are still gender differences that have been found. Men are more likely than women to imagine being in a dominant or active role, whereas women are more likely to imagine themselves as passive participants. [42] Women's fantasies have significantly more affection and commitment, [43] whereas men are more likely to fantasise using visual imagery and explicit detail. [44] [45] One explanation of this difference comes from the evolutionary perspective. Women have a higher minimum parental investment than males (they have 9 months of gestation prior birth and are then the main care givers, whereas men only have to provide sperm to ensure their genes are passed on) and are therefore more likely to want commitment from their partner in order to gain resources to improve their offspring's chance of survival. [46]

Fantasies can have benefits, such as increasing arousal more than other forms of sexual stimuli (such as an erotic story) and increasing sexual desire. [47] [48] Individuals who disclose their sexual fantasies to their partners also have a higher sexual satisfaction. However, whether people are willing to open up to their partner generally depends on the content of such fantasies. [49] A more negative effect of sexual fantasy is that it has been linked with sexual crimes, and indeed sexual offenders often report that they have had fantasies related to their offense. [42] However, such fantasies are also common among those who have not been involved in such criminal acts [42] and non-offenders do not use their fantasies to guide their behaviour. [50] Therefore, fantasy alone cannot be used as a sign that someone will become an offender. [42]

Dreams

Nocturnal emission orgasms or "wet dreams" or "erotic dreams" are when people ejaculate or orgasm during sleep. [51] These occur during REM (rapid eye movement) phases of sleep, [41] which is the main stage when humans dream. [52] This implies that erotic dreams alone are enough to stimulate men, but erections accompany all REM phases. [41] According to self-report data, as many as 22% of young women may also experience orgasm during sleep, with such dreams being more common in college students in higher school years than younger students. [53] The orgasms experienced were positively correlated with high emotionality, including sexual excitement, but also anxiety. [53]

Sexual role-play

Sexual role-play is when people act out characters or scenarios which may sexually stimulate each other. This can include fantasies (discussed above) and fetishes, such as BDSM (bondage and discipline, dominance and submission, sadism and masochism) or age-play. It has been described by some as an adult form of L.A.R.P (live action role-play). [54] Role-play can also be carried out online, by typing stories to each other or pretending to be a character, and is therefore a form of mental stimulation you can engage in with another person without them being physically present. Many adolescents find online role-play pleasurable and arousing. [55]

Role-play can also include sexual fan fiction, where characters from well-known stories, that were not sexually or romantically together in the original story, are written into sexual scenes. Slash fiction is a type of fan fiction where the characters of the same sex (originally male-male) engage in romantic or sexual activities. Slash fiction allows people the freedom to share stimulating things that can be counter-cultural. [56]

Role of sexual dysfunctions in sexual stimulation

Women

Physiological factors

According to the National Library of Medicine, approximately 80% of middle aged women with heart failure have reported a decrease in vaginal lubrication, leading to challenges in successful intercourse. [57] The reduction in lubrication affects the vaginal moisture during sexual activity. Women with hypoactive sexual desire (HSDD) may also experience a lack of interest in sexual stimuli, thus affecting their psychological responses to sexual cues. [57]  Within the study conducted by Sandra Garcia and her colleagues, suggested that trauma-related changes may impact genital tissues, affecting blood flow and response to sexual stimulation. [58]  As well as when psychologic distress is present it affects the ability to achieve orgasm despite adequate sexual stimulation. [59] This is a result of relationship issues that affect sexual stimulation and sexual response, connecting back to orgasmic difficulties. [59]

Hormonal factors

The deficiency of estrogen leads to conditions like dyspareunia, which is something important for maintaining adequate lubrication. [60] Therefore there is hormonal treatment that is used which is the addition of in-taking estrogen supplements. [60]  But as well as the supplementation of testosterone, which was shown as beneficial for enhancing desire, arousal, and sexual satisfaction. [60]  There could also be some hormonal changes when it comes to going through the phases of aging. A review in 'The Journal of Sexual Medicine', showed how pre-menopause women showed more sexual dissatisfaction. This was shown due to their hormonal imbalances. [61]

Responses to sexual stimulation

Brain

When sexual stimulation is perceived, there are systems in the brain that receive the stimuli and respond to it. During physiological sexual arousal, the autonomic nervous system responds to signals from central nervous system and prepares the body for sexual activity. [62] The autonomic nervous system engages the parasympathetic and sympathetic systems, which are responsible for blood flow to genital and erectile tissues, and to muscles that participate in sexual responses. [62] This results in responses like increased breathing rate, heart rate, and pupil dilation. The limbic system also plays a part in how sexual stimuli are received. [63] A study done about pleasure and brain activity in men showed that electrical stimulation of the limbic system is highly pleasurable, and can sometimes generate orgasmic responses. [63] During genital stimulation different areas of the brain are activated in men and women. For men, a study saw that genital stimulation caused part of the cerebral cortex and the insula, which is a part of the sympathetic and parasympathetic systems, to activate. [64] For women, during clitoral stimulation parts of the secondary somatosensory cortex were activated. [64] In both men and women the amygdala was deactivated. [64]

Induced ovulation

Some mammal species are induced ovulators, requiring stimulation of the genitals during copulation in order to ovulate. [65]

Orgasm or sexual climax is the sudden release of accumulated sexual excitement during the sexual response cycle, characterized by intense sexual pleasure resulting in rhythmic, involuntary muscular contractions in the pelvic region. Orgasms are controlled by the involuntary or autonomic nervous system and experienced by both males and females; the body's response includes muscular spasms, a general euphoric sensation, and, frequently, body movements and vocalizations. The period after orgasm is typically a relaxing experience, after the release of the neurohormones oxytocin and prolactin, as well as endorphins.

<span class="mw-page-title-main">G-spot</span> Hypothesized anatomical detail

The G-spot, also called the Gräfenberg spot, is characterized as an erogenous area of the vagina that, when stimulated, may lead to strong sexual arousal, powerful orgasms and potential female ejaculation. It is typically reported to be located 5–8 cm (2–3 in) up the front (anterior) vaginal wall between the vaginal opening and the urethra and is a sensitive area that may be part of the female prostate.

<span class="mw-page-title-main">Foreplay</span> Intimate acts that create sexual arousal

Foreplay is a set of emotionally and physically intimate acts between one or more people meant to create sexual arousal and desire for sexual activity. Although foreplay is typically understood as physical sexual activity, nonphysical activities, such as mental or verbal acts, may in some contexts be foreplay. This is typically the reason why foreplay tends to be an ambiguous term and means different things to different people. It can consist of various sexual practices such as kissing, sexual touching, removing clothes, oral sex, manual sex, sexual games, and sexual roleplay.

<span class="mw-page-title-main">Nipple</span> Part of the breast

The nipple is a raised region of tissue on the surface of the breast from which, in lactating females, milk from the mammary gland leaves the body through the lactiferous ducts to nurse an infant. The milk can flow through the nipple passively, or it can be ejected by smooth muscle contractions that occur along with the ductal system. The nipple is surrounded by the areola, which is often a darker colour than the surrounding skin.

<span class="mw-page-title-main">Sexual fetishism</span> Sexual arousal a person receives from an object or situation

Sexual fetishism or erotic fetishism is a sexual fixation on a nonliving object or body part. The object of interest is called the fetish; the person who has a fetish for that object is a fetishist. A sexual fetish may be regarded as a mental disorder if it causes significant psychosocial distress for the person or has detrimental effects on important areas of their life. Sexual arousal from a particular body part can be further classified as partialism.

<span class="mw-page-title-main">Doggy style</span> Sex position

Doggy style is a sex position in which one participant bends over, crouches on all fours, or lies on their abdomen, for sexual intercourse, other forms of sexual penetration or other sexual activity. Doggy style is a form of rear-entry position, others being the spoons sex position in which the receiving partner lies on their side or the reverse cowgirl sex position. Non-penetrative sex in this position may also be regarded as doggy style.

<span class="mw-page-title-main">Sexual desire</span> Psychological feature arousing organisms to physical pleasure and reproduction

Sexual desire is an emotion and motivational state characterized by an interest in sexual objects or activities, or by a drive to seek out sexual objects or to engage in sexual activities. It is an aspect of sexuality, which varies significantly from one person to another and also fluctuates depending on circumstances.

Erotic massage is the use of massage techniques by one person on another person's erogenous zones for their sexual pleasure. The process may achieve or enhance the recipient's sexual excitation or arousal and sometimes achieve orgasm. The person providing the massage is called a masseur (male) or masseuse (female). Massages have been used for medical purposes for a very long time, and their use for erotic purposes also has a long history. In the case of women, the two focal areas are the abdomens and pubis, while in case of men, the focal areas are the male breast muscles and nipples, male genitals, the anus, and the prostate. When the massage is of a partner's genitals, the act is usually referred to as a handjob for penises and fingering for vulvas.

<span class="mw-page-title-main">Erogenous zone</span> Area of heightened sensitivity of the body, touching which may elicit a sexual response

An erogenous zone is an area of the human body that has heightened sensitivity, the stimulation of which may generate a sexual response such as relaxation, sexual fantasies, sexual arousal, and orgasm.

Persistent genital arousal disorder (PGAD), originally called persistent sexual arousal syndrome (PSAS), is spontaneous, persistent, unwanted and uncontrollable genital arousal in the absence of sexual stimulation or sexual desire, and is typically not relieved by orgasm. Instead, multiple orgasms over hours or days may be required for relief.

The human sexual response cycle is a four-stage model of physiological responses to sexual stimulation, which, in order of their occurrence, are the excitement, plateau, orgasmic, and resolution phases. This physiological response model was first formulated by William H. Masters and Virginia E. Johnson, in their 1966 book Human Sexual Response. Since that time, other models regarding human sexual response have been formulated by several scholars who have criticized certain inaccuracies in the human sexual response cycle model.

Sexual arousal disorder is characterized by a lack or absence of sexual fantasies and desire for sexual activity in a situation that would normally produce sexual arousal, or the inability to attain or maintain typical responses to sexual arousal. The disorder is found in the DSM-IV. The condition should not be confused with a sexual desire disorder.

<span class="mw-page-title-main">Erotic talk</span> Practice of using explicit word imagery to heighten a type of arousal

Erotic talk, also known as dirty talk, gross talk, love talk, naughty talk, sexting, sexy talk, talking dirty, or talking gross, is the practice of using explicit word imagery to heighten sexual excitement before and during physical sexual activity. It is commonly a part of foreplay, and can include vivid erotic descriptions, sexual humor, sexual commands and rude words. It may be whispered into a partner's ear, spoken over a telephone, or put into text. The intention of erotic talk is generally to generate excitement between one, both or all parties engaged in a sexual interaction, or even to induce orgasm.

Erotic lactation is sexual arousal by sucking on a female or male breast. Depending on the context, the practice can also be referred to as adult suckling, adult nursing, and adult breastfeeding. Practitioners sometimes refer to themselves as being in an adult nursing relationship (ANR). Two persons in an exclusive relationship can be called a nursing couple

Various aspects and dimensions of female sexuality, as a part of human sexuality, have also been addressed by principles of ethics, morality, and theology. In almost any historical era and culture, the arts, including literary and visual arts, as well as popular culture, present a substantial portion of a given society's views on human sexuality, which includes both implicit (covert) and explicit (overt) aspects and manifestations of feminine sexuality and behavior.

<span class="mw-page-title-main">Sexual arousal</span> Physiological and psychological changes in preparation for sexual intercourse

Sexual arousal describes the physiological and psychological responses in preparation for sexual intercourse or when exposed to sexual stimuli. A number of physiological responses occur in the body and mind as preparation for sexual intercourse, and continue during intercourse. Male arousal will lead to an erection, and in female arousal, the body's response is engorged sexual tissues such as nipples, clitoris, vaginal walls, and vaginal lubrication.

<span class="mw-page-title-main">Sexuality after spinal cord injury</span> Aspect of human sexuality

Although spinal cord injury (SCI) often causes sexual dysfunction, many people with SCI are able to have satisfying sex lives. Physical limitations acquired from SCI affect sexual function and sexuality in broader areas, which in turn has important effects on quality of life. Damage to the spinal cord impairs its ability to transmit messages between the brain and parts of the body below the level of the lesion. This results in lost or reduced sensation and muscle motion, and affects orgasm, erection, ejaculation, and vaginal lubrication. More indirect causes of sexual dysfunction include pain, weakness, and side effects of medications. Psycho-social causes include depression and altered self-image. Many people with SCI have satisfying sex lives, and many experience sexual arousal and orgasm. People with SCI may employ a variety of adaptations to help carry on their sex lives healthily, by focusing on different areas of the body and types of sexual acts. Neural plasticity may account for increases in sensitivity in parts of the body that have not lost sensation, so people often find newly sensitive erotic areas of the skin in erogenous zones or near borders between areas of preserved and lost sensation.

<span class="mw-page-title-main">Nipple stimulation</span> Human sexual practice

Nipple stimulation or breast stimulation is stimulation of the breast. Stimulation may be by breastfeeding, sexual activity, an indirect non-sexual response, or kissing the nipple. As part of sexual activity, the practice may be performed upon, or by, people of any gender or sexual orientation. It may occur with the use of fingers, orally, such as by sucking or licking, as well as by use of an object.
