Research has shown that the sexual effects of alcohol are different for men and women. This is likely the result of both physical and social differences in the way womens bodies and mens bodies react to alcohol and respond sexually.
Not surprisingly, the amount of alcohol consumed has a large impact on whether there will be negative sexual effects of alcohol for women. Most of the research in this area has been with women who are, or were alcoholics. The main effects for these women of alcohol on sexuality are:
- Reduced sexual arousal
- Difficulty achieving orgasm, achieving orgasm less frequently
- Overall lower sexual satisfaction as compared to non-alcoholics
The actual number of alcoholic women who have these difficulties is hard to tell, as researchers numbers vary wildly. Some estimates are as high as 30-40% of alcoholic women having arousal problems, and 15% having difficulty achieving orgasm.
In another study of 74 alcoholic women in rehab, 41% reported some negative sexual effects from drinking (interestingly, 49% of the women reported positive sexual effects).
Contradictions in the reported sexual effects of alcohol on women
There is a contradiction in the research on alcohols effect on womens sexuality. Research indicates that even after one drink alcohol reduces a womans physical sexual response. Vasocongestion and vaginal lubrication both progressively decrease with alcohol consumption. But several studies have shown that women both expect and report higher levels of sexual arousal when alcohol is involved.In one laboratory study of 18 women who masturbated while their sexual arousal was being measured, the researchers found that women who had consumed some alcohol (but were still under the legal limit (0.08% to 0.10%) had decreased vaginal blood measures, took longer to reach orgasm, and had decreased intensity of orgasm. But these same women subjectively reported that their sexual arousal and orgasmic pleasure increased at higher levels of alcohol consumption.
Explaining the contradiction
Its worth noting that this is no the only area of sex research where physiological measurements and subjective reporting are different. Its possible that the way we measure sexual response doesnt correspond to the way people actually experience it (in other words: its not all about genital blood flow and heart rate). Its also possible that women are expecting positive sexual effect from alcohol and are uncritically interpreting whats going on in a way that meets their expectations.
But there are other important considerations. In another large study, which included a nationally representative sample, more than half the women reported that sexual activity was more pleasurable when they drank. The real question we should be asking is not what is it about alcohol that makes women report this, but why might women find sex more pleasurable when they have been drinking?
Is it possible that being raised in a sex phobic culture makes it difficult for women (and likely men too) to enjoy sex when they are fully conscious? Is it possible that the disinhibiting effects of alcohol are required for people to let their guard down enough to have satisfying sex? These would be difficult things to prove, but they are worthwhile questions, and if there is any truth to them its a sad comment on our societies approach to sexuality.
Is alcohol really courage in a bottle?
The adage that alcohol is liquid courage is probably the basis for many drinks imbibed. But one study suggests that this is a misguided effort. In this study, where women kept a log of both drinking and sexual activity, the only significant difference between the three groups (women who drank no alcohol, moderate drinkers, and heavy drinkers) was that female initiated sexual activity happened more when women werent drinking. This study is one of the few that didnt rely on retrospective accounts of sexual behavior, and here the greatest amount of sexual initiation took place in the absence of alcohol.
