Let's see. Met Ralph Woods in Montreal once. Very nice guy, seems well put together and polite, appears to have a good head on his shoulders. And of course he's gorgeous, and has a great cock - which I (unfortunately!) did not see in person.
I used to work out at a gym in Boston which is now closed. I was using the urinal there one day when I noticed the guy next to me looking at my cock...and realized it was Dawson. I told this story to an acquaintance and he noted that he was actually a friend of Dawson's and that he had a real job (at the time) which was entirely not porn-related, and that he was a really sweet, innocent, down-to-earth guy.
Another Boston guy who went into porn I believe now goes (went? not sure he still does porn) by Jason Tyler. Sorry to be blunt but, he's an asshole.
A very good friend of mine was once very good friends with the guy who now calls himself Chad Brock. Met "Chad" a few times and he seemed like a really sweet, charming guy who also had a lot of issues. I think when my friend caught on to the fact that "Chad" was making porn, their friendship dissolved as I haven't heard my friend talk about him much recently.
Watching an SX video preview one time, there was a clip of a hot mixed/Asian looking bottom getting pounded and I thought "Hm, I fucked him at Steamworks in Chicago a few years ago." (And he was fun, by the way.)
I have heard that three other people I know have done porn, but don't know their assumed names or the vids they've been in.
