How many men have you allowed to grab YOUR crotch?
As for me, NONE!
Having looked at the 12-second clip, 1) it doesn’t look like the other guy asked permission, 2) although my vision is somewhat impaired, it looked like a half-hearted motion lacking any contact, and 3) it looked like they were making a joke.
The other 30-second video is more disturbing, raising more serious questions. In isolation, the 12-second clip is just stupid kids horsing around.
