Hookup

Any advice for someone new to hookup? So I've started hooking up multiple times with the same guy, and we're aware that it's just all about sëx, he told me not to fall in love with him which I was always been aware of bc I had to think harder before agreeing to meet him. We had amazing sëx, he's good at what he is doing and I like it that way, but sometimes he'd say something I think he shouldn't be saying like "You're mine and only mine" I don't appreciate that phrase bc we're just hooking up, he'd also do stuff that I think we shouldn't be doing like him giving me a kiss and a hug after picking me up and before he dropped me home, he'd feed me and make stuff. I don't know if that's just normal, but I want all of it to be all about sex and nothing else and I'm sure he wants the same thing as well, but yeah idk I'm new to this hookup era I'm just trying to detached myself and I cant do that if I don't know the normal and mixed signal action.
