Playing along with this absurd hypothetical I think the right thing to do is choose A. For evolutionary reasons, and everything I've read seems to confirm for me that rape is much worse for a woman than a man.

Because A is ugly and has low standards she will experience the least discomfort from sleeping with your friend. As you said, and I think correctly, the pleasure of banging a hot girl isnt as serious as the discomfort for a girl of being forced to sleep with someone you dont want.

Basically its the woman who is getting psychologically messed up here and the guy wont suffer much from having to bang an ugly girl. In fact I'd rather bang an ugly girl that wanted me. Being forced to rape even a hot girl would obviously be horrible.
