I don’t care but just wondering since his computer is in the living room of our apartment and the apartment is small, is it wrong of me to ask him not to jerk off when I’m home? I just can’t fall asleep feeling like I can’t go to the bathroom or get water when I want in fear of walking out to him. I don’t wanna control him or anything but I rather him do it when I’m not home or in a locked room. Is this reasonable?
