Why do guys stop after hooking up?

I’ve wanted just a friends with benefits lately but guys would stop hitting me up after a couple times. We’re still on good terms but I wouldn’t see them anymore. Do they think I want more which pushes them away? and need to be more direct of what I want.
This one guy I recently hooked up with we would hang out first everytime and end the night cuddling at his place and get intimate. I’m not trying to get serious if that’s not his intentions and wouldn’t mind just a friends with benefits thing.
