I had a dream last night that I was on a riverside licking a girl's anus. I know it sounds strange but what the hell does this mean?
It means that some of the sexual stuff you're hearing about from the other guys is grossing you out but your conscious mind can't admit to it because you want to believe you're a cool guy, 'fitting in'.
Your hormones perhaps. You're beginning to desire sexual actions maybe.
sexual expression is my guess
