ingrown hairs/bumps

I've been wanting my SO to give me head for a while now, but everytime he offers I turn him down because I'm self conscious about the red bumps and ingrown hairs that I get from shaving for him! I want to be confident and look past it but I can't help but feel like he's gonna look at me like I have a gross vagina or an std or something's wrong with me. What should I do?
