Buck Angel isn't a women, and neither is his vagina. His genitals are male-gendered because his gender is male. I don't know if you were referring to Buck Angel, or muscular women with that first statement, but I thought I'd clarify.
There is gender, and there is sex. The more important factor here is gender, not sex. The reasoning for this is because humans adapt culturally. We experience this culture through society. This is why biological sex is less important than socially-centered gender. It is gender that is part of how our society is structured, and not biological sex. Does that make sense?
The "look at male in jealousy" concept makes sense because our societal structure is so hegemonic. It is very easy to relate to other males in a vertical scale, such as being jealous of one in the act of sex.
I DEFINITELY agree with the big clits comment. I also fantasize about watching a hot guy eat a pussy out with pleasure. I'm not sure what turns me on about it exactly, but I do enjoy it, partially I think because he is enjoying it as well. I love to see him fool around with his tongue too.
Personally, I hate when porn videos cut to women's faces. It turns me off and pisses me off simultaneously. I don't give a shit about her face...only her vagina and boobs, sometimes her ass. I'm not trying to be insulting, that's just how I feel...
