So desperation just really isn't for me. Watching videos of people squirm just makes me impatient and jump to the end. However, I recently found that (once I skip the holding) I LOVE videos of boys in white briefs or boxer briefs soaked in yellow pee. When he then pulls out his cock and masturbates I'm in heaven. In this case, the bigger the cock the better. If he doesn't cum I feel really let down. Jeans don't do it for me.
Before, I thought that I didn't get turned on by male piss at all; I typically watch lesbian pee porn. Pee from a pussy is just much more appealing and sexual (IMHO) while pee from a penis is just....normal/not erotic? What I mean is that a guy holding his cock and pissing is what he does day in and day out, but when females do it we squat, stand, spread our legs, etc. in ways that are more intimate.
However, now I know that if I don't actually see the piss coming out of the cock I'm all for it and very excited by it. Although it really turns me on, I still don't think I would ever let a self-wetting boy fuck me. I would want him to lick me or maybe I would be the one to turn his briefs yellow. ;)
