This is an interesting question that can tell you a lot about how your brain works.
It's funny, because to me, the reason is irrelevant. I don't care why she does it, if it happens. If it's for love, that offends me, but if it's for fun, it makes it to where I can't respect her because she's a slave to her urges. Both reasons make me sick.
Sorry to give you a copout answer.
