I entered 90% straight and 10% gay mainly because I like to look. I'm much more choosy about what I like with men than with women.
Men- Mostly the only thing I care about on a man is a big dick. I don't really get much reaction out of the rest of the body. Seeing a big dick just makes my dick hard too. I don't know why, but it works. I'm turned on by comparing. I think, "Oh yea, that's a big dick alright, but what about this one? Yea, I think mine is bigger"... makes me rock hard. The combination of a big dick and hot girl is the best. If I watch porn and the guy's dick is not adequate to my tastes, then it does me no good. I do admire a fit muscular male body and a handsome face, but that doesn't really arouse me sexually. Also, I can look at a man and develop my own opinion about whether he is good looking or not. I've heard some men homophobicly try to dodge the question when asked if another man looks good. However, whether we admit it or not, I think it is a property of most people that we gravitate toward others who look good whether they be men or women. Finally, the behavior of men often annoys me and I don't find it attractive. I have a lot of DISLIKES about men in the appearance and personality department. I find the personalities of men to be better suited as friends.
Women- In the right woman, I love every last detail about her. Physically, I love the obvious focal points, genitals, breasts, butts. One other thing I absolutely love about a woman's body is that hourglass curve where the hips curve in to the waist and it gets really narrow right about the belly button. God, I love that. Just seeing that one curve turns me on so much. Another one is womens necks. I like that area from right behind the ear down. If I see a girl with her hair up I always check out that little area below her ear. I don't know what it is, I just get the urge to put my mouth on a woman's neck. I love women's faces, usually very distinct from a man's. A woman with long beautiful hair is very attractive to me, though I have seen some very cute girls with shorter hair too. I love women's voices. I'm attracted to women's feminine behavior. I like girls to act like girls. I find the behavior of women to be better suited to real partnerships for me instead of shallow friendships. It's like a girls personality better compliments my own.
I've given it plenty of consideration. I like women a lot and men a little. I'm also a strong believer in biology. Men and women evolved to fuck each other. You can be homo if you like, but if we give up on hetero, then we have reached the end of humanity or either some kind of 1984/Brave New World oddity. I believe that everything about me was created to get a woman pregnant and help her raise my children. There is no way that I can deny that I am supposed to be with a woman. However, that doesn't rule out finding some form of pleasure in both men and women. These are the things that I think about when saying 90/10%.
