What are we?

So there is this guy I️ like who I️s a year older than me (I️m 17), we have been hooking up the past couple of months (haven’t had sex yet). We never talk at school but we are super close out of school. We are currently talking about becoming exclusive and I️m not sure what I️ want and neither is he. I️ hate the idea of him getting with other girls but I️ still wanna be able to get with other guys. Ik this prob sounds super slutty but whatever lol. He said pretty much the same exact thing so where does that leave us? We both definitely don’t wanna date but don’t know if we should be exclusive or not. Any thoughts??
