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.
You're insane. Please, please, seek therapy. You clearly have a brain but something terrible must have happened to you, and I'm sorry for that, but you need to find help.
You cannot equate "Would you marry an ex-child molester?" and "Would you marry someone who has had casual sex?"
Cannot.
CANNOT.
One raped a fucking child, dude. RAPED. A. CHILD. Another had a consensual relationship with another willing adult. You cannot and should not equate the two just because you happen to disagree with both. That is plain and outright creepy.
Otherwise you're just trying to fulfill a shopping list, and it's not going to work out for anyone.
