So just because he hasn't beaten any of them when they come after him, means he hasn't been r*ped? We haven't seen him give consent, but we have seen him protest, say no, and no means no.
How strong do we know that he is? He seems inexhaustible while using the AFT, and has incredible strength when throwing it. But we haven't seen anything about his strength when he isn't using the AFT, he might be just as weak as a regular untrained man, while the women (vampire, angel, maaany high elves) are magical beings, demonic beings, they seem to have a lot of strength, if not physical, then magical, if not both.
Even if someone doesn't show their trauma, doesn't mean they don't gave any!
