What sexual moment did you think I shouldn't do this, but then said screw it and did it anyway?

I'm sure each of us have been at cross roads where we shouldn't have done something but couldn't control our desires and just gave in to our impulses and the heat of the moment. What moment or moments was it for you where you forgot rationality or indulged in your sexual desires even when you shouldn't have?

Mine would be hooking up with someone while staying at a resort for a destination wedding. Even went to doing things in the bathroom while my cousins and brother was fast asleep on my bed.
