Hey guys, OP here
I was just putting my arm around the girl from behind, my whole front and her back were in contact, and my thing was right where her ass was, we were kind of grinding too. I think she felt it but didn't say anything and we kept dancing.
So should I say anything if I do get a hard-on? I broke up with my girlfriend about 2 months ago and I miss having sex a lot... just trying out clubbing scene to see where it leads me
