How to tell a guy I’ve romantically talked to I just want to hookup?

Hooked up with a guy I talked to for a while and was nice to me/took me on sweet dates. It was more of a fuck it I just want to end my celibacy streak and not let the last guy I ever fuck be my ex thing. Guy thinks we’re dating and I haven’t said no because the sex was good but I know I’m not emotionally available. He sent me flowers today and wants to go kayaking this weekend with me but I just want to keep hooking up and not spend time together anymore.
