I feel suffocated

I feel like he's too clingy! I need a lot of space by myself, but my friend set me up on a blind date with this guy 4 days ago. (Lockdown has been lifted in NZ)

We clicked, and I invited him over to my place. We didn't have sex because I didn't want to. Then the next morning he proceeded to stay til 8pm. That is 2 full days with him already. After he left, he asked me if he could come over at 12. He literally just left?

I said no, but asked if we could hang out the next day. I agreed but didn't expect him to stay over again.

This is 4 days in a row of me seeing him. He cuddles so much at night, and I normally don't want to cuddle when I actually want to sleep. I don't know what to do. He touches me a lot and I don't like being touched that much. At first I liked him, but this much cuddling and meeting every single day is such a turn off and I feel suffocated.

He even asked if he can come over tonight. He just left 30 mins ago! This is driving me crazy. What should I do?
