Make sure that both you and the woman are truly making a conscious decision to sleep together. Remember that quality sex works best when the body and the mind are on the same page. This means thinking carefully about what you’re doing before you take that first drink. Talk to the woman you’re with before she starts drinking, too. Otherwise, you may end up doing something you’ll regret later. You don’t want this to turn into a messy situation in a legal sense, so the thought of all of that hassle alone may help you avoid drinking to the point of limpness.
Wear a condom that fits well. The little things can make a difference when you’ve been drinking, and a condom that’s too large or too small can throw you off of your game. If you’re not sure, don’t be afraid to try on a few different sizes and brands before heading out for a night of drinking. This might seem embarrassing, but you’ll thank yourself later. Also, when you’re actually with a woman, don’t try to rush and get it on. Being flustered will make it harder to perform.
