You’ve probably been in this situation: You’ve had one too many drinks, take her back to your place, and realize you just can’t get hard. Thank whiskey dick, one of the most unfortunate curses to fall on mankind.
Alcohol is a depressant on your central nervous system, says Dr. Brahmbhatt. It decreases blood flow to your penis, which can prevent you from getting hard.
So while that drink might relax you enough to get her into bed—and it’s true, some guys might perform better with a tiny bit of booze in their system—it might prevent you from getting the job done if you go overboard, he says.
So be conscious of your limitations: Guys should stick to roughly two drinks per day, according to the Centres for Disease Control and Prevention. While everyone’s tolerance is different, it’s a good benchmark to keep in mind if you plan on doing the deed once you get back home.
