Consent must be actively given each time, not assumed from past agreements. Saying "don't ask, just do it" once doesn't mean it applies later. Treating prior agreements as blanket permission can lead to sexual assault.
If your partner tells you, don't ask, just do it. I want you to dominate me. Yeah, in that moment they do. In that moment they do. But might they feel the same way tomorrow when you're in the mood? Are they going to feel the exact same way all the time? Yes or no? No. Now you make the move. Do we have trouble? Yeah, because you taught each other this really dangerous game. That this is how we're going to treat each other. I'm going to guess with your body and now you're ticked at me and I followed the rules you gave me and we got a disaster. And by the way, it's still sexual assault because there's no consent there. You can't consent the day before. It's not how it works. So that's a disaster.
