Straight up, just like the question says. No grinding, just dancing. A friend and me were arguing about it. He says they do, I'm not sure, of course, he has been with a lot more girls than I have. To picture you a scenario: I had a few drinks and I'm dancing with this really attractive girl. My hands are in her waist, she smells really good and she is moving really sexy. Is it bad that I have an erection? I mean, what can I do about it anyway?
