Some things are unacceptable, though. Casual sex is one of them.

Would you marry an ex-child molester? Assume he claimed to be reformed, and that he didn't do it anymore, and that it was something he only did when he was intoxicated and "caught up in the moment" (whatever that means).

Obviously, the reasonable answer is no. Nobody wants to marry someone who's done something like that in his or her past. Experiences and past behaviors matter.

Now you understand how normal men feel about casual sex.
