Alcohol and sex deals with the effects of the consumption of alcohol on sexual behavior. [2] The effects of alcohol are balanced between its suppressive effects on sexual physiology, which will decrease sexual activity, and its suppression of sexual inhibitions. [3] A large portion of sexual assaults involve alcohol consumption by the perpetrator, victim, or both. [4]
Alcohol is a depressant. After consumption, alcohol causes the body's systems to slow down. Often, feelings of drunkenness are associated with elation and happiness but other feelings of anger or depression can arise. Balance, judgment, and coordination are also negatively affected. One of the most significant short term side effects of alcohol is reduced inhibition. Reduced inhibitions can lead to an increase in sexual behavior. [3]
Low to moderate alcohol consumption is shown to have protective effect for men's erectile function. Several reviews and meta-analyses of existing literature show that low to moderate alcohol consumption significantly decreases erectile dysfunction risk. [5] [6] [7] [8]
Men's sexual behaviors can be affected dramatically by high alcohol consumption. Both chronic and acute alcohol consumption have been shown in most studies [9] [10] [11] (but not all [12] ) to inhibit testosterone production in the testes. This is believed to be caused by the metabolism of alcohol reducing the NAD+/NADH ratio both in the liver and the testes; since the synthesis of testosterone requires NAD+, this tends to reduce testosterone production. [13] [14]
As testosterone is critical for libido and physical arousal, alcohol tends to have deleterious effects on male sexual performance. Studies have been conducted that indicate increasing levels of alcohol intoxication produce a significant degradation in male masturbatory effectiveness (MME). This degradation was measured by measuring blood alcohol concentration (BAC) and ejaculation latency. [15] Alcohol intoxication can decrease sexual arousal, decrease pleasureability and intensity of orgasm, and increase difficulty in attaining orgasm. [15]
In women, the effects of alcohol on libido in the literature are mixed. Some women report that alcohol increases sexual arousal and desire, however, some studies show alcohol lower the physiological signs of arousal. [16] A 2016 study found that alcohol negatively affected how positive the sexual experience was in both men and women. [17] Studies have shown that acute alcohol consumption tends to cause increased levels of testosterone and estradiol. [18] [19] Since testosterone controls in part the strength of libido in women, this could be a physiological cause for an increased interest in sex. Also, because women have a higher percentage of body fat and less water in their bodies, alcohol can have a quicker, more severe impact. Women's bodies take longer to process alcohol; more precisely, a woman's body often takes one-third longer to eliminate the substance. [20]
Sexual behavior in women under the influence of alcohol is also different from men. Studies have shown that increased BAC is associated with longer orgasmic latencies and decreased intensity of orgasm. [16] Some women report a greater sexual arousal with increased alcohol consumption as well as increased sensations of pleasure during orgasm. Because ejaculatory response is visual and can more easily be measured in males, orgasmic response must be measured more intimately. In studies of the female orgasm under the influence of alcohol, orgasmic latencies were measured using a vaginal photoplethysmograph, which essentially measures vaginal blood volume. [16]
Psychologically, alcohol has also played a role in sexual behavior. It has been reported that women who were intoxicated believed they were more sexually aroused than before consumption of alcohol. [16] This psychological effect contrasts with the physiological effects measured, but refers back to the loss of inhibitions because of alcohol. Often, alcohol can influence the capacity for a woman to feel more relaxed and in turn, be more sexual. Alcohol may be considered by some women to be a sexual disinhibitor. [16]
Some studies have made a connection between hookup culture and substance use. [21] Most students said that their hookups occurred after drinking alcohol. [21] [22] [23] Frietas stated that in her study, the relationships between drinking and the party scene and between alcohol and hookup culture were "impossible to miss". [24]
Studies suggest that the degree of alcoholic intoxication in young people directly correlates with the level of risky behavior, [25] such as engaging in multiple sex partners. [26]
In 2018, the first study of its kind, found that alcohol and caffeinated energy drinks is linked with casual, risky sex among college-age adults. [27]
Alcohol intoxication is associated with an increased risk that people will become involved in risky sexual behaviors, such as unprotected sex. [15] Both men, [28] and women, [29] reported higher intentions to avoid using a condom when they were intoxicated by alcohol.
Coitus interruptus , also known as withdrawal, pulling out or the pull-out method, is a method of birth control during penetrative sexual intercourse, whereby the penis is withdrawn from a vagina or anus prior to ejaculation so that the ejaculate (semen) may be directed away in an effort to avoid insemination. [30] [31] Coitus interruptus carries a risk of STIs and unintended pregnancy. This risk is especially high during alcohol intoxication because lowered sexual inhibition can make it difficult to withdraw in time.
Women with unintended pregnancies are more likely to smoke tobacco, [32] drink alcohol during pregnancy, [33] [34] and binge drink during pregnancy, [32] which results in poorer health outcomes. [33] (See also: fetal alcohol spectrum disorder)
Rape is any sexual activity that occurs without the freely given consent of one of the parties involved. This includes alcohol-facilitated sexual assault which is considered rape in most if not all jurisdictions, [35] or non-consensual condom removal which is criminalized in some countries (see the map below).
A 2008 study found that rapists typically consumed relatively high amounts of alcohol and infrequently used condoms during assaults, which was linked to a significant increase in STI transmission. [36] This also increases the risk of pregnancy from rape for female victims. Some people turn to drugs or alcohol to cope with emotional trauma after a rape; use of these during pregnancy can harm the fetus. [37]
One of the most common date rape drugs is alcohol, [39] [40] [41] administered either surreptitiously [42] or consumed voluntarily, [39] rendering the victim unable to make informed decisions or give consent. The perpetrator then facilitates sexual assault or rape, a crime known as alcohol- or drug-facilitated sexual assault (DFSA). [43] [35] [44] Many perpetrators use alcohol because their victims often drink it willingly, and can be encouraged to drink enough to lose inhibitions or consciousness. [45] However, sex with an unconscious victim is considered rape in most if not all jurisdictions, and some assailants have committed "rapes of convenience" whereby they have assaulted a victim after he or she had become unconscious from drinking too much. [46] The risk of individuals either experiencing or perpetrating sexual violence and risky sexual behavior increases with alcohol abuse, [47] and by the consumption of caffeinated alcoholic drinks. [48] [49]
Non-consensual condom removal, or "stealthing", [50] is the practice of a person removing a condom during sexual intercourse without consent, when their sex partner has only consented to condom-protected sex. [51] [52] Purposefully damaging a condom before or during intercourse may also be referred to as stealthing, [53] regardless of who damaged the condom.
Consuming alcohol can be risky in sexual situations. It can impair judgment and make it difficult for both people to give or receive informed sexual consent. However, a history of sexual aggression and alcohol intoxication are factors associated with an increased risk of men employing non-consensual condom removal and engaging in sexually aggressive behavior with female partners. [54] [55]
The use of alcohol is a documented factor in wartime sexual violence.
For example, rape during the liberation of Serbia was committed by Soviet Red Army soldiers against women during their advance to Berlin in late 1944 and early 1945 during World War II. Serbian journalist Vuk Perišić said about the rapes: "The rapes were extremely brutal, under the influence of alcohol and usually by a group of soldiers. The Soviet soldiers did not pay attention to the fact that Serbia was their ally, and there is no doubt that the Soviet high command tacitly approved the rape." [56]
While there wasn't a codified international law specifically prohibiting rape during World War II, customary international law principles already existed that condemned violence against civilians. These principles formed the basis for the development of more explicit laws after the war, [57] including the Nuremberg Principles established in 1950.
A study published in 2003 supported the beer goggles hypothesis; however, it also found that another explanation is that regular drinkers tend to have personality traits that mean they find people more attractive, whether or not they are under the influence of alcohol at the time. [58] A 2009 study showed that while men found adult women (who were wearing makeup) more attractive after consuming alcohol, the alcohol did not interfere with their ability to determine a woman's age. [59]
A 2021 study found that bar patrons rated themselves as more attractive towards the end of the night, regardless of their level of intoxication, and that this effect had more to do with motivations to attract a mate. The "closing time effect" was tested in Danish bars, with researchers separating responses based on whether bar patrons had filled out their survey in the afternoon, evening, or night, and finding that people attending the bar at night rated themselves as more attractive than earlier visitors. [60]
In psychology, libido is psychic drive or energy, usually conceived of as sexual in nature, but sometimes conceived of as including other forms of desire. The term libido was originally developed by Sigmund Freud, the pioneering originator of psychoanalysis. With direct reference to Plato's Eros, the term initially referred only to specific sexual desire, later expanded to the concept of a universal psychic energy that drives all instincts and whose great reservoir is the id. The libido - in its abstract core differentiated partly according to its synthesising, partly to its analytical aspect called life- and death-drive - thus becomes the source of all natural forms of expression: the behaviour of sexuality as well as striving for social commitment, skin pleasure, food, knowledge and victory in the areas of species- and self-preservation.
An aphrodisiac is a substance alleged to increase libido, sexual desire, sexual attraction, sexual pleasure, or sexual behavior. These substances range from a variety of plants, spices, and foods to synthetic chemicals. Natural aphrodisiacs, such as cannabis or cocaine, are classified into plant-based and non-plant-based substances. Synthetic aphrodisiacs include MDMA and methamphetamine. Aphrodisiacs can be classified by their type of effects. Aphrodisiacs that contain hallucinogenic properties, such as bufotenin, have psychological effects that can increase sexual desire and sexual pleasure. Aphrodisiacs that have smooth muscle relaxing properties, such as yohimbine, have physiological effects that can affect hormone concentrations and increase blood flow.
Alcohol abuse encompasses a spectrum of alcohol-related substance abuse, ranging from the consumption of more than 2 drinks per day on average for men, or more than 1 drink per day on average for women, to binge drinking or alcohol use disorder.
Sexual dysfunction is difficulty experienced by an individual or partners during any stage of normal sexual activity, including physical pleasure, desire, preference, arousal, or orgasm. The World Health Organization defines sexual dysfunction as a "person's inability to participate in a sexual relationship as they would wish". This definition is broad and is subject to many interpretations. A diagnosis of sexual dysfunction under the DSM-5 requires a person to feel extreme distress and interpersonal strain for a minimum of six months. Sexual dysfunction can have a profound impact on an individual's perceived quality of sexual life. The term sexual disorder may not only refer to physical sexual dysfunction, but to paraphilias as well; this is sometimes termed disorder of sexual preference.
A date rape drug is any drug that incapacitates another person and renders that person vulnerable to sexual assault, including rape. The substances are associated with date rape because of reported incidents of their use in the context of two people dating, during which the victim is sexually assaulted or raped or suffers other harm. However, substances have also been exploited during retreats, for example ayahuasca retreats. The substances are not exclusively used to perpetrate sexual assault or rape, but are the properties or side-effects of substances normally used for personal recreation or medical purposes. One of the most common incapacitating agents for date rape is alcohol, administered either surreptitiously or consumed voluntarily, rendering the victim unable to make informed decisions or give consent.
An anaphrodisiac is a substance that quells or blunts the libido. It is the opposite of an aphrodisiac, something that enhances sexual appetite. The word anaphrodisiac comes from the Greek privative prefix ἀν-, denoting negation, and aphrodisiac, from the Greek goddess of love, Aphrodite. Some people use anaphrodisiacs in order to curb a very high libido or due to hypersexuality. However anaphrodisiacs are also used by those with an average libido, at times due to having incessant schedules.
Alcohol has a number of effects on health. Short-term effects of alcohol consumption include intoxication and dehydration. Long-term effects of alcohol include changes in the metabolism of the liver and brain, with increased risk of several types of cancer and alcohol use disorder. Alcohol intoxication affects the brain, causing slurred speech, clumsiness, and delayed reflexes. There is an increased risk of developing an alcohol use disorder for teenagers while their brain is still developing. Adolescents who drink have a higher probability of injury including death.
Sex and drugs refers to the influence of substances on sexual function and experience. Sex and drugs date back to ancient humans and have been interlocked throughout human history. Sexual performance is known as the execution of the act of sex and the quality of sexual activity. This includes elements such as libido, sexual function, sensation. Drugs are termed as any chemical substance that produces a physiological and or psychological change in an organism. Drugs categorized as psychoactive drugs, antihypertensive drugs, antihistamines, cancer treatment, and hormone medication have a significant impact on sexual performance. Various drugs result in different effects, both positive and negative. Negative effects may include low libido, erection issues, vaginal dryness and anorgasmia. Positive effects usually address these issues, overall enhancing sexual performance and contributing to a more enjoyable sexual experience. It is crucial to know that the impact of drugs on sexual performance varies among individuals, especially among different genders.
Rape is a traumatic experience that affects the victim (survivor) in a physical, psychological, and sociological way. Even though the effects and aftermath of rape differ among victims, individuals tend to suffer from similar issues found within these three categories. Long-term reactions may involve the development of coping mechanisms that will either benefit the victim, such as social support, or inhibit their recovery. Seeking support and professional resources may assist the victim in numerous ways.
The sexuality of US adolescents includes their feelings, behaviors and development, and the place adolescent sexuality has in American society, including the response of the government, educators, parents, and other interested groups.
Alcohol myopia is a cognitive-physiological theory on alcohol use disorder in which many of alcohol's social and stress-reducing effects, which may underlie its addictive capacity, are explained as a consequence of alcohol's narrowing of perceptual and cognitive functioning. The alcohol myopia model posits that rather than disinhibit, alcohol produces a myopia effect that causes users to pay more attention to salient environmental cues and less attention to less salient cues. Therefore, alcohol's myopic effects cause intoxicated people to respond almost exclusively to their immediate environment. This "nearsightedness" limits their ability to consider future consequences of their actions as well as regulate their reactive impulses.
Binge drinking, or heavy episodic drinking, is drinking alcoholic beverages with an intention of becoming intoxicated by heavy consumption of alcohol over a short period of time, but definitions vary considerably.
Alcohol-related crime refers to criminal activities that involve alcohol use as well as violations of regulations covering the sale or use of alcohol; in other words, activities violating the alcohol laws. Underage drinking and drunk driving are the most prevalent alcohol-specific offenses in the United States and a major problem in many, if not most, countries worldwide. Similarly, arrests for alcohol-related crimes constitute a high proportion of all arrests made by police in the U.S. and elsewhere.
Hookup culture is one that accepts and encourages casual sex encounters, including one-night stands and other related activity, without necessarily including emotional intimacy, bonding or a committed relationship. It is generally associated with Western late adolescent sexuality and, in particular, United States college culture. The term hookup has an ambiguous definition because it can indicate kissing or any form of physical sexual activity between sexual partners. The term has been widely used in the U.S. since at least 2000. It has also been called nonrelationship sex, or sex without dating.
Alcohol, sometimes referred to by the chemical name ethanol, is the second most consumed psychoactive drug globally behind caffeine, and alcohol use disorders are the most prevalent of all substance use disorders worldwide. Alcohol is a central nervous system (CNS) depressant, decreasing electrical activity of neurons in the brain. The World Health Organization (WHO) classifies alcohol as a toxic, psychoactive, dependence-producing, and carcinogenic substance.
Risky sexual behavior is the description of the activity that will increase the probability that a person engaging in sexual activity with another person infected with a sexually transmitted infection will be infected, become unintentionally pregnant, or make a partner pregnant. It can mean two similar things: the behavior itself, and the description of the partner's behavior.
Non-consensual condom removal, or "stealthing", is the practice of a person removing a condom during sexual intercourse without consent, when their sex partner has only consented to condom-protected sex. Purposefully damaging a condom before or during intercourse may also be referred to as stealthing, regardless of who damaged the condom.
Marijuana use is commonly thought to enhance sexual pleasure. However, there is limited scientific research on the relationship between marijuana and sex. The lack of research on the topic is, in part, due to U.S. drug policies centred on prohibition. In addition, the effects are difficult to study because sexual arousal and functioning are, in themselves, extremely complex and differ among individuals. Moreover, marijuana affects people differently. As a result, it is challenging to study. Men and women report greater sexual pleasure after having consumed marijuana, but there is no direct scientific evidence of the effects on the physiological components of the sexual response cycle when using the drug.
Drugs and sexual consent is a topic that discusses the impacts of drugs on sexual activity that lead to changes in sexual consent. Sexual consent is the voluntary agreement to engage in sexual activity, which is essential in preventing sexual violence. Consent can be communicated verbally or nonverbally and should be freely offered. However, drug use, particularly psychoactive drugs that alter mental processes, can affect people's decision-making and consent communication ability, potentially impacting the autonomous aspect of sexual consent.
Alcohol and society are closely intertwined, as it is widely consumed and legally permitted in most countries around the globe, despite its potential to lead to various issues. According to a 2024 World Health Organization (WHO) report, these harmful consequences of alcohol use result in 2.6 million deaths annually, accounting for 4.7% of all global deaths.
