Man, thanks to webchats and sites like LPSG.org I have come to the conclusion that all of us males feel turned-on in some degree to manhood. One could imagine a scale going from 2 males beeing complementary in sex, to others where the turn-on is for admiration and identification, to some others where is the worship of a thing lacked in himself.
For myself, I'm very turned on by the sight of a big nice cock, its spurts of cum, and the overall apearance of the male body it is attached, none detail in special in that body. Could look at a pic of a nice package without its body and j/o to it for hours. Nowadays I consider frotting a hot thing to think of, but never realy had the chance to experiment it a lot. BUT any thought of penetrative sex w/ men is a big TURN OFF for me.
With women on the other hand, most of my thoughts are about shoving my dick inside a pussy, an ass or a mouth, I NEED TO BE INSIDE OF THEM, as if my cock were craving for a hot, moist tight place to hide. This craving for beeing inside a girl is directly proportional to the shape of her body (her ass specially), how much breast her clothes show, her wal, her smile. BUT I don't get any significant excitement from a pic of a pretty cunt without some of the girls body and preferably her face (at LEAST a pussy pic showing her breasts also).
Maybe we'll never find out if we are str8 or gay because we can't find where in this scale we fit (I filleed the form 50% str8 / 50% gay here and I'm a 28y/o adult, so...), maybe we are equaly as excited by femaleness and maleness. Maybe labels are just dull.
