I am not into asses sexually (Greek) but visually, I don't think there is anything more erotic and stimulating than a great ass. Why? Interesting question. I think it has to do with a great ass usually projecting the prospect of great sex. But, does that mean that a less than great ass leads to less than great sex? Personally I have had some great sex from Providers with less than stellar asses, therefore I believe it is purely a visual stimulant, but what a great one it is. Here is a compilation of some of my favorite asses. Hope you are visually stimulated.
