OP....I agree with you. I've done anal to a few woman, used toys on their ass (all with there permission and encouragement) but did nothing for me. In fact, more often that not, there was little bits of dirt on the toys, or condom on my cock (I won't bareback anything/anyone, let alone an ass) - I can understand it from a 'dominance' perspective, and even the woman offering up her ass-- I'm also very sensitive to smells....and nothing kills a mood faster for me than the smell of pee or poop... I like clean body parts.
