My favourite thing is just seeing a guy's cock chub up with anticipation, watching it throb and spring up excitably. Even better if some precum leaks out.
I'm young but hairy and extremely horny. I love being naked especially seeing other people naked too. I love casually spending naked time with someone and just seeing where it develops. My cock is sensitive and quite hyperactive. If I'm turned on, it's gonna start bouncing and throbbing like crazy.
I have a girlfriend who doesn't know I am interested in guys, and so I expect discretion, also some patience as I can't always meet up. I will always let you know in advance if I have a change of plans.
