I like women and I like men; sexually, both of them turn me on. I am NOT attracted to women who are more "masculine" nor to men who are more "feminine," although I do understand that those are culturally normative labels for behavior. But, like the OP, I do not understand nor like it when a man calls his ass a pussy. If I'm with a man, I am with him BECAUSE he is that--a man. I like the sweaty, visceral, earthy feel (and smell) of m2m sex. And, like another poster on here said, an ass doesn't feel like a pussy at all (IMHO).
I understand why women are attractive as they are attractive TO ME. I like the soft, feminine, and yin to my yang. That's very appealing to me when I'm with a woman. But, hell, if I'm with another man, avoid "baby, pussy, girl, etc." Call me "man, bud, dude, or whatever" (my name would be appropriate), but do not call me girl.
I guess I like to be in the moment and enjoying it, not pretending I'm doing something else--like having sex with a woman (or man) when I'm doing the opposite.
