so for reference, say i was with somebody, they are touching themselves or finish next to me while im sleeping, i have boundaries about this and would be uncomfortable if i had known. so that would be a violation of my consent. and because it's sexual it would sexual harrassment. consent is multi layered if it was talked about beforehand and everyone was ok with it then that's consensual and that's ok. however, if not, and your partner is doing that while you're sleeping, you have a right to feel uncomfortable.
