Definitely no face slapping. A pretty face shouldn’t be struck. If the face isn’t pretty, it doesn’t belong in an erotic video. Friendly slapping to the body (like after a fall) can be nice, and I always wonder whether it might sting the recipient a bit much for her taste, leading to some sort of escalation. One thing that could be sexy is open hand palm strikes to the body. Could that be integrated into erotic wrestling?
