Denying a drunkard's offer does not really make you "a pussy", you know? What're ya, a fratboy?
If she still wants to bone him after she's sober, though, that's a completely different story. In that case, the only way he'd end up being a total puss, is if he'd both go completely with her flow, but end up pussying out at the very last moment.
Either go whole way, or tell her straight off the bat that he's not interested. Indecisive characters are a pain.
