Does he just like fantasizing about me, or is it more?

My ex friend with benefits from 7 years ago told me he remembers every time we had sex... in GREAT detail.

We're still good friends, but he's been married now for a few years. Drunkenly one night recently, he told me that he pictures sleeping with me a lot (like every time he jerks off). Does he just remember those times fondly, or does he possibly have some problematic feelings?
