Alcohol and sex deals with the effects of the consumption of alcohol on sexual behavior. The effects of alcohol are balanced between its suppressive effects on sexual physiology, which will decrease sexual activity, and its suppression of psychological inhibitions, which may increase the desire for sex. 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. In men 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 decrease erectile dysfunction risk. Men's sexual behaviors can be affected dramatically by high alcohol consumption. Both chronic and acute alcohol consumption have been shown in most studies (but not all) 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. 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. Alcohol intoxication can decrease sexual arousal, decrease pleasureability and intensity of orgasm, and increase difficulty in attaining orgasm. In women 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. A 2016 study found that alcohol negatively affected how positive the sexual experience was in both men and women. Studies have shown that acute alcohol consumption tends to cause increased levels of testosterone and estradiol. 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,
