I get it. Most men, gay or straight, are exactly like you. I can’t tell you how many gay men have said to me, “Eww, the very idea of doing anything with a women totally grosses me out, and I have never had one ounce of desire for a woman.” All I am saying is that I think it is totally presumptuous to say that EVERYONE is the same as you. Sprague would be an example of someone who does not fit in those black and white boxes. There are LOTS of people in the world who don’t fit in the boxes, including many who always have physical relations one way or another but may get occasional twinges inside their heads.
I agree with you. Sexuality can be a very grey area.
One of my friends has been gay since high school, we all knew he was gay but he didn't come out until he was 30. Was married and had two kids. Now he's 45 and lives with his male "partner". He openly admits that he finds both male and females attractive still today.
A guy i worked with years ago was gay and had been with his male partner for 10 years. Both were very attractive guys who were successful Architects. They used to pic up chicks at clubs, take a bunch of X and tag team them all night. Both admitted they found women physically attractive, but not mentally attractive.
I dated a girl for almost a year who played both sides of the field. Took turns dating men and women. Said the same thing, men are better for physical attraction, but women were better "lovers".
