Alcohol: A couple of drinks can loosen your inhibitions and help you relax. But alcohol can also impair sexual functioning. Alcohol works on the nervous system by slowing down brain function, breathing, and pulse. Initially, the effect is often psychologically stimulating, since emotions and desires flow more freely.

For this reason, it's best for guys to limit their alcohol intake to one to two drinks (or none at all) for optimal sexual function.
