I find that I last a lot longer, get harder and my sexual performance is increased when I get a bit tipsy. There is the increased confidence and lack of inhibitions that come with it too.
What do you find the effects of alcohol to be on your sexual performance? I was under the impression that it would reduce sexual performance but for me there is the opposite effect; maybe it's just because my own bar is very low to begin with (premature ejaculator etc.) :)
