Late to the party.
Adam Russo - very good lay. Great kisser. As I recall he enjoyed doing poppers with me.
Buster Sly - I'm normally not into AA men (just a preference) but I thought an old video of his where he and a hot Hispanic dude played with a Fleshlight was so erotic that I used to frequently jack to it, thus he got a visit from me when he was in town. He was a lot of fun, too, but I honestly can't remember a ton of details.
There was one more daddy type porn star, but I can't remember his name. Huge cock with a P.A. I honestly was not really into it. I have not seen his RM for awhile but either he or someone who stole his photos is on Grindr.
