No one particular dude on Maskerbate is that sexy, imho. JP is the only one, and just a little bit. BUT, I'm not a fan of gay porn in general (exceptions). Male solos are sometimes sexy (it's like watching yourself masturbate), but the dude has to have unique features (big dick, attitude, etc.). I usually just go back to straight or lesbo porn. LOL.
Best gay porn ever is from Eastern Europe, if you're into gay porn, that is. The dudes are natural in body and masculinity.
^ Just my big-dick opinion. LOL.
