It's a sort of self punishing. He doesn't want to feel emotional pain so he channel's it to rough sex and physical pain instead. He tells himself it feels good over and over again which i don't doubt he feels pleasure but its a sort of protective mantra.
Am I understanding correctly? He’s sad, and is coping by…… taking a big ass dick?
This will make himself feel better? ( ̄∇ ̄")
