I think that sometimes its the curiosity of it that drives the whole thing - after a while you get to a seen-it-all point, and the variation is another progression in that.

I know a few trannys, both FTM and MTF, who are in relationships with both straight and gay guys as both hetero and homo pairings from the respective adopted sex, and they seem to do fine. However, i do find my self wondering how long it took to get used to, as a gay guy to sleep with a guy who used to be a girl who has no breasts and a vagina....

The one that i dont get is sneaker fetish, i can understand smells, feet, and jockstraps and stuff, but jerking off all over a pair of vintage Adidas, I dont get in the slightest.
