Friend's sister - Definitely. I don't understand why guys get pissed at other guys who bang their sister. It's completely irrational, and if you're going to end a friendship over it, then you're probably not someone I'd get along with anyway.
Friend's wife/girlfriend - No way. I'm pretty much up for anything with anyone, but this would bother even me too much.
