My best friend is a swinger. Totally into the life style. And completely uncreepy about it, unlike the lefttoids I know who somehow manage to give off major porno creep vibes.
My buddy every other year or so will simply, "Hey, just curious if you and the wife ever changed your mind about, you know, maybe going to Italy or something and fuckin? No? Okay, cool, I respect that."
I asked him once why he never invited just me to come over and dick down his wife.
"That'd be weird man, we know you and know you'd be going behind your wife's back to do that and that's just not right."
