I understand what your saying Wayne, and for the most part agree with you. It's really fairly similar to some of my gay friends that tell me they'd probably puke if they had to have sex with a woman. I'm way too far toward the middle of the scale to find sex with either sex vomit enducing.
gato, in general women are just not as carefree about sex as men. Hmmm, maybe the pregnancy thing has something to do with that? Maybe being thought of as loose? Gay guys can pretty much just say to each other "Hey wanna hit it", and if they're both mutually attracted to each other exchanging names isn't even that important. At least that's how it was in my day, but I'm old. Believe it or not, even easy, carefree sex can get old after some time.
