Generally speaking, guys will not touch a woman in a porn theater unless invited. If invited, the men will take all the woman is willing to give. My wife fucked a guy in a porn theater last year. I had already eaten her out and fucked her. We were relaxing while this Latino guy asked if he could sit next to her. We said OK, and he proceeded to fondle her very gently (which she likes). He very gently stroked her clit, and she was all "Let's fuck!" I had to make sure he put on a condom, because she was past thinking of anything but having a dick in her. He was a little fatter than I am, and she was a little apprehensive, but she had a huge orgasm.
It happens a lot. Check out
