Alcohol and Sex 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.

Were dead and damned, there sounded ‘War is done!’

‘Will men some day be given to grace? yea, wholly,
And in good sooth, as our dreams used to run?’”
