I must have this person blocked because I can't see who created it. Sounds like something the kitteh would ask.
But regardless, ironically a dude's ass doesn't smell or taste like shit (not that I would know what that tastes like) unless he's unclean. If his ass does smell bad I'm certainly not going to put my mouth there. If it's not good enough for my nose it's not good enough for my tongue. One of the guys I'm currently seeing has an ass that smells like an armpit which drives me nuts. Not sure how that happens but love it.
