He likes me but I don't want to hurt him.?

this guy has asked me for my number and been texting me for a few days I don't really see my self dating him or even have a lot of feelings for. He is just not the type of guy I would go for looks wise.. His personality is really nice and I like how he notices me but I feel like maybe I could do better almost.. I don't want to be mean and maybe I could like him if I give him a chance but what if I don't then it's gonna suck to let him down. Plus I have never had a boyfriend and what if I should just take it..?
