I'm with you 100% on the rimming. I like a lot of different ass shapes and sizes, but a flat, flabby ass is a deal breaker for me. I've even gotten to like a number of guys with hairy asses, lately, but they have to have a nice shape. I tend to like smooth guys, since I'm hairy. I like hairy guys, too as long as they have a sexy hair pattern. No gorillas for me, sorry. I just happen to like the feel of smooth skin when I'm exploring their bodies with my mouth. There's no right or wrong. Everyone has the right to like what they like. No two people have the exact same taste in anything. What I don't like is when people try to dictate to others what they should like. Nobody is asking them and it's none of their business.
Now one other thing, that's not related to body parts, but someone who can't dance, and I mean no rhythm, not fancy moves, is also kind of a turnoff. For me, dancing is very sensual and sexual. If they can't even follow a beat, it doesn't give me much hope for the way they would be in bed.
Getting back to rimming...I could make a 9 course meal out of a hot, receptive hole. Ooooh baby! But, clean is a must. A little sweaty is fine. In fact, I love that manly taste, but not dirty, if you get my drift.
