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 will 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 == Men's sexual behaviors can be affected dramatically by alcohol. Both chronic and acute alcohol consumption have been shown in most 〔 〕〔 〕 (but not all〔 〕) studies 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.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Alcohol and sex」の詳細全文を読む スポンサード リンク
