To be fair, your base point is that discovering sexuality isn't like taking your temperature. There's lots of factors and as we grow, our sexual tastes change. I'll always like men but the kinds of men I'm into can change.
Well, no, not really, though I do appreciate your rereading/thinking about my initial post. My point was that some of us, in the process of coming out/discovering our sexuality, have a harder time circumventing our inhibitions against gayness, and what is often the LAST one to go is the taboo of male affection, i.e., "man love." You can suck and be sucked, fuck and be fucked, but the minute it becomes "romantic," you're no longer a man. Sex is sex, but the kissy stuff="sissy-boy"=WRONG.
But what happens on porn sites shouldn't be taken as indicative of real life.. you may see a guy go from a solo to bottoming over the course of 5 months but those scenes were usually all shot the same weekend.
Indeed (and those are usually the most obvious and WORST, btw), but what I'm thinking about are the guys who are GENUINELY uncomfortable with their sexuality, who do gradually warm up to their own freakiness. Example: a few years back, there was a
Sean Cody model named Luke. He was so uncomfortable in his first vid, Sean had to go out of the room, set up a still camera to record the pop shot. A few vids later, and Sean is giving Luke a massage. Luke rolls over, and is hard as a rock. Stays that way the rest of the video. He is clearly into what Sean is doing, so much so that he lets Sean kiss him, and he kisses back. A LOT. It's one of the most erotic vids I own. (and if it were fake, well, they did a pretty DAMN good job of faking it)
Another, far disparate example is Chris Rockway. The boy is clearly hetero. I can't even imagine the fistfuls of Viagra the boy has to take to perform. But I saw him take it up the ass on film LONG before I saw him kiss another guy.
