Yep, a person certainly is allowed to revoke consent. I was trying to address the "but what about those 24/7 people over there, or the Goreans over there!" case, as I believe people see that as the dom/owner making all decisions for the couple, and I think it's important to understand that those situations are pre-negotiated and based on choice. You're absolutely right though that even pre-negotiated consent can be withdrawn at any time. I'll stand by the statement that if consent is not granted or is withdrawn that a dom has options ranging from expressing displeasure through ending the relationship, but does not have the option of forcing himself on a sub.
