Guys, What does it mean when he remembers every single detail about you sexually?

This is for men only, so this guy I've been involved with on and off for the last 4 years literally always describes detail for detail about our sex life. At first I was flattered but now I'm like ok why are you still talking about it in so much detail. He talks about the way I feel the noises I make and how wet I am sometimes I don't even think that he remembers but he always does then he talks about it. My question is why is he doing this so much and with so much detail? Is he mentally ill or something.
