Is it weird to start pet names?

So a couple weekends ago I met this guy and we went out last weekend with a group of friends then it just ended up being me and him later in the night. I had so much fun with him and like him. I feel like I’m afraid of coming off too strong because I already said I liked everything about him. But idk anyways ,, when is it too soon to use like names like hun, babe? Would it be a good thing to do this soon over text or no?
