I'm ... one of the few men who is intelligent enough to know that sex is as fun and totally natural with a man or a woman.
I don't think one's sexual attraction has anything to do with intelligence. To suggest that non-bisexuals aren't as intelligent or even as open-minded is just silly. People can prefer whatever they like!
Anyway, onto the topic at hand. I am 100% straight, but there is nothing attractive about the pussy, visually speaking. It is great to touch (in several ways), but to the view... not so much.
I would think it would be obvious that virtually everyone on this site, given its name, would find cocks pleasing to the eye, whether they're attracted to them or not. When I see a nice cock, I feel like I'm admiring a nice sculpture or a work of art, not that I want to feel it or do something with it.
With that in mind, a cock is far more pleasant to look at than a pussy, even though I have no personal attraction for it. The rest of the female body? Well, that's another story all together! :wink:
