i have the same kind of thoughts. i think i am more straight than not, but yeah, i think about my mates naked or seeing them naked and get turned on by that. wtf.
i've often fantasized about it. likely could never be the one to bring it up, but if asked i would strongly consider...especially if asked by one of the guys i fantasize about.
i can understand, but it's the erect size that is really more important. not really anything you can do to change it, so you needs to accept it and learn to like it. hey, it's who you are.
