How to stop my boyfriend buying me so many gifts? Im not materialistic n its making me feel really awkward...?

Me n my boyfriend have been dating only a few months, this might seem a weird issue but he keeps buying me gifts like every time. Im grateful but Ive told him he doesnt have to n id prefer to just have a nice time together. Im.not materialistic n I like everything to be 50/50 in a relationship. When we go for food or drink we pay half n take turns, same if we go cinema or somewhere. I dont have as much money as him although ive bought him.something when I went away one weekend and something for xmas I could never do it as much as he does for me and I think he would feel rralllyeally uncomfortable if I did.I dnt like being showered with material.objects, ive never been that type of person. It just makes me feel awkward n kinda bad. Ive asked him to stop but he keeps on. I dnt like that he seems to think being a boyfriend is about buying stuff, but whatever I say he keeps doing it.
