Angry Grimace
Two cannibals are eating a clown. One turns to the other and says "does something taste funny to you?"
It's only rape if you say no? She TOLD him under what conditions he could have sex, he agreed. And then he lied. Sorry, no.
Actually, legally speaking, it's not really a debatable question. The legal rules for how fraud affects rape are generally universally accepted and well understood; it's called fraud in the factum vs. fraud in the inducement.
Fraud only vitiates consent in rape cases when the fraud relates directly to the thing done, in other words, fraud in the factum. Fraud in the inducement is fraud relating to a "collateral" matter - whether he was wearing a condom or had herpes would assuredly be considered collateral.
