In amniotes, the clitoris is a female sex organ. In humans, it is the vulva's most erogenous area and generally the primary anatomical source of female sexual pleasure. The clitoris is a complex structure, and its size and sensitivity can vary. The visible portion, the glans, of the clitoris is typically roughly the size and shape of a pea and is estimated to have at least 8,000 nerve endings.
The labia minora, also known as the inner labia, inner lips, or nymphae, are two flaps of skin that are part of the primate vulva, extending outwards from the inner vaginal and urethral openings to encompass the vestibule. At the glans clitoris, each labium splits, above forming the clitoral hood, and below the frenulum of the clitoris. At the bottom, the labia meet at the labial commissure. The labia minora vary widely in size, color and shape from individual to individual.
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.
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.
A wet dream, sex dream, or sleep orgasm, is a spontaneous occurrence of sexual arousal during sleep that includes ejaculation and orgasm for a male, and vaginal lubrication and/or orgasm for a female.
Erectile tissue is tissue in the body with numerous vascular spaces, or cavernous tissue, that may become engorged with blood. However, tissue that is devoid of or otherwise lacking erectile tissue may also be described as engorging with blood, often with regard to sexual arousal.
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.
Tumescence is the quality or state of being tumescent or swollen. Tumescence usually refers to the normal engorgement with blood of the erectile tissues, marking sexual excitation, and possible readiness for sexual activity. The tumescent sexual organ in males is the penis and in females is the clitoris and other parts of the genitalia like the vestibular bulbs. Arteries in the penis dilate to increase blood volume.
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.
The urethral sponge is a spongy cushion of tissue, found in the lower genital area of females, that sits against both the pubic bone and vaginal wall, and surrounds the urethra.
Fingering is sexual stimulation of the vulva or vagina by using the fingers. Vaginal fingering is legally and medically called digital penetration or digital penetration of the vagina. The term "digital" takes its significance from the English word 'digit', which refers to a finger, thumb, or toe. Fingering may also include the use of fingers to stimulate the anus.
In female anatomy, the vestibular bulbs, bulbs of the vestibule or clitoral bulbs are two elongated masses of erectile tissue typically described as being situated on either side of the vaginal opening. They are united to each other in front by a narrow median band. Some research indicates that they do not surround the vaginal opening, and are more closely related to the clitoris than to the vestibule. They constitute the root of the clitoris along with the crura.
Nocturnal penile tumescence (NPT) is a spontaneous erection of the penis during sleep or when waking up. Along with nocturnal clitoral tumescence, it is also known as sleep-related erection. Colloquially, the term morning wood, or less commonly, morning glory is also used, although this is more commonly used to refer specifically to an erection beginning during sleep and persisting into the period just after waking. Men without physiological erectile dysfunction or severe depression experience nocturnal penile tumescence, usually three to five times during a period of sleep, typically during rapid eye movement sleep. Nocturnal penile tumescence is believed to contribute to penile health.
A G-spot vibrator is a sex toy with female and male varieties. The female version of the device is built to massage the G-spot, described as a bean-shaped area of the vagina. Some women report that it is an erogenous zone which, when stimulated, can lead to strong sexual arousal, powerful orgasms and female ejaculation. The male version of the G-spot vibrator is used for massaging the prostate for both sexual and health-related reasons.
An erection is a physiological phenomenon in which the penis becomes firm, engorged, and enlarged. Penile erection is the result of a complex interaction of psychological, neural, vascular, and endocrine factors, and is often associated with sexual arousal, sexual attraction or libido, although erections can also be spontaneous. The shape, angle, and direction of an erection vary considerably between humans.
Human female sexuality encompasses a broad range of behaviors and processes, including female sexual identity and sexual behavior, the physiological, psychological, social, cultural, political, and spiritual or religious aspects of sexual activity. 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.
Clitoral erection is a physiological phenomenon where the clitoris becomes enlarged and firm.
The mechanics of human sexuality or mechanics of sex, or more formally the biomechanics of human sexuality, is the study of the mechanics related to human sexual activity. Examples of topics include the biomechanical study of the strength of vaginal tissues and the biomechanics of male erectile function. The mechanics of sex under limit circumstances, such as sexual activity at zero-gravity in outer space, are also being studied.
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.
Penile-vaginal intercourse or vaginal intercourse is a form of penetrative sexual intercourse in human sexuality, in which an erect penis is inserted into a vagina. Synonyms are: vaginal sex, cohabitation, coitus, intimacy, or (poetic) lovemaking. It corresponds to mating or copulation in non-human animals.
