Is it wrong to just want sex and not an actual relationship?

Basically I’ve been with this guy for over a month. He is great but our relationship isn’t. I can see the cracks already so early on. I have spoken to him about the issues and he has agreed that I am right and that it doesn’t even feel like we are in a relationship.

The sex is great, but am I wrong to want just that and nothing else?

P. S don’t bother commenting if you’re gonna be rude. Thanks & bye 👋🏼
