@DW2 Alcohol just lowers your inhibitions, opening you up to do things that you do want to do but would otherwise hold yourself back from. So anytime someone says "I was drunk, I did not mean that," they are wrong. They really meant it, it just came out of hiding.
So anytime a woman claims she had sex, cheated, or did any other thing but did not really want to do it and only did it because she was drunk, she is lying. Because she did want to do that.
@DW2 In non-sexual examples, I know of guys who become violent when they are drunk. It turns out that such men are violent. Some men get very sad when they are drunk. It turns out, they have major problems and are indeed sad but not hiding it.
Some are more harmless and just silly. Those are not as big of a concern, though they can be obnoxious.
