Sorry, but that's not normal and healthy - that's non-consensual (not to mention unprotected) sex! You should never proposition a drunk person, but from what I read here there wasn't even any propositioning, just sex without informed consent beforehand - i.e. rape! It doesn't matter if she didn't mind afterwards, because what if she had? He never even asked! This sends a message that it's okay to fool around with a drunk girl, which is NEVER true!
