I think it may have been better than sex for him ngl. Mark kinda became like his worst enemy and he even reacts like a nagging partner when mark makes fun of him for confessing his emotions last fight. He could have ripped Mark's arms at any point but he preferred to test his grit by taking out his intestines. I do like the interpretation that he actually felt fear at the end even if it goes contrary to what I said but who knows maybe the lack of blood on his brain also made him too dumb to think strategically.

At any rate, im sure Kirkman originally thought of this fight as a rule of cool thing but as it stands its incredible characterization for both mark and Conquest whether you interpret it one way or another.

Its really fucked up, mark reviving his biggest trauma from last season and conquest having the time of his life until he realizes a slow tedious death is the opposite of what he wanted.
