Setting Ground Rules During Rough Sex

i asked my partner, what do you think about setting some ground rules before we go to make sure that we're both comfortable with whatever happens. And he was ako, love it. Whatever makes you feel safe. So i asked him if he would be ok with us not doing anything with any one else and just if they came to the point where we are comfortable enough to do stuff ourselves or people watch. He said yes. We set some rules around, you know, if you leave me for any reason to go to the bathroom, like, make sure you ask me twice, just to be tht i'm ok being left alone. It's kind of like having a safe word
