I have dabbled a bit, but nothing "intense."  I absolutely love to see and feel a bulge in a pair of briefs (something about what's unseen but so very evident), and have had the chance to worship (orally) a ball sac a few times (my favorite activity).  Not really into giving orally, but I do enjoy receiving oral, and love getting rimmed.  Can't really call myself a "top" or "bottom" because I still consider myself a novice at this.  Enjoy seeing a man pleasure himself, and body to body contact with kissing is most desirable.  Let's snuggle and spoon!
