I don't personally mind incest, so long as it's consensual and you don't reproduce. What people do behind closed doors really isn't any of my business!
TO add to the friends dating friend's exes, i'm firmly against it. It's painful if someone breaks up with you and finds your friend attractive.
My old best friend from HS never even liked the girl. Was just an easy on and easy off for him. A GF I had in HS broke up with me and had a fling with him. It fucking sucked. Felt awful.
Incest is a completely unsuitable topic for this forum. Closing this.
CLOSED.
