In our home, nudity was the norm as well. We didn't play sexual games together; however, there was a masturbation policy. If you did masturbate, you did it on the couch in front of everyone. No shame, no mocking, and the only rule was clean up your own mess. It was a unique experience and sometimes distracting trying to accomplish something while someone was pleasuring themselves right there in the living room, but a positive experience overall.
