what to do?

There's this guy I met through my cousin and I honestly think I'm crushing HARD!! We started texting a month ago and we have already had sex 4 times, the sex is amazing but I'm starting to like him and I don't know how to tell him. I think he feels the same but I'm to scared to ask and I think he's to scared to tell me. I'm not use to a guy acting this way with me I'm so used to them chasing me so I'm stuck. What if he doesn't feel the same? I don't want him to reject me but I can't keep having sex with him if we aren't on the same page 😩 help me out, what to do?
