Depends on the hug. Hug a friend parent coworker etc. then no it doesn't and hasn't happened. But a really good long hug tight against my girlfriend can do the trick. I mean come on her hips are against me and her chest against mine. She doesn't seem to mind at all though.
i try to keep it back, cause id be embarrassed if I had one, and she could feel it, I mean how would you feel if we could feel that you were wet, lol, anyway, yeah, I mean if she's being so seductive etc... that I can't hold it back then she's got no choice but to feel it, when we hug, but like I said, I'm pretty good at keeping it back
I don't feel it because he usually doesn't have an erection when he hugs me. (as in my bf) I have not felt one from a friend either. But my boyfriend did joke one time when I was startled that something moved down there (near his pocket): "Oh my penis just moved." It was his cell vibrating. hahaha
