That's a tough one , but I would assume they would actually have to catch you in the act . ie. bust down the front door , then the one to your room , and find your Johnson in a place it wasn't supposed to be . If not , then you were just getting a massage , and they can't prove any different !! Only 2 of you were in the room , and I seriously doubt the girl is going to tell on herself .
That being said , they could still probably make you do the perp walk for the cameras . Never mind that we are all innocent , until we have our day in court . Once your face hits the news , everyone assumes you are guilty anyway .
