((Just need some advice on my boyfriend and our sex life))

Okay so, this guy i’ve been with for a while now, has made it clear that he doesn’t want to eat pussy. I’ve given him head numerous times and have tried to hint that I want the favor in return but he just won’t. I feel like im missing out on a lot since i haven’t experienced that part yet. I also feel that maybe it Isn’t fair ? Should I feel ashamed that maybe it’s my body ?? I do love him but I feel like putting a boundary on our sex
