Uninvited touching is never okay. I would step back and remind him that it was creepy. And I am a gay man.
I agree. There's many ways to connect with people and non verbally too that are available to communicate intent and consent, and a well mannered and conscientious man is able to make a discrete erotic inquiry eyes only and fast discrete and unobtrusive with a response given equally smoothly. Anything else is disruptive in most of nude culture and certainly this isn't the behavior that is anticipated nor appreciated by most men at most times, is considered assault in a M F context and is effectively the same thing here, so why ask the question?
