Tips and Guidelines for Open Masturbation

I am looking for a nudist roommate, and I am wondering if anyone has any advice for implementing an open masturbation policy? I know that it is something that people recommend on here, but I've never done anything like this, so I was wondering if anyone has any advice. Like, do you just jerk off in the open while your roommate has dinner in the living room? What rules do you suggest? Also, does anyone have any tips for how to bring it up to a potential nudist roommate?

Thanks!
