What do i do if i excite a guy?

Awkward moment: I'm hanging out with a guy at a party and I'm dared to rub up on him and make horny sounds. I do it, but I swear I felt something hard in his pants. They were really baggy, so you couldn't see, but I could swear I gave him an erection....

He's my friend, and its just between the two of us, but things are kind of awkward between us now. What should I do???

Play it off because what would you expect whenever you rub up on a guys crotch? I know a gay guy that got a hard on at a female strip club whenever he got a lap dance. I was just the feeling.

yep, just laugh. don't worry.
