Selfish lover anything else I can possibly do?

I'm 22 and my partner is 25. We have been together for 3 years and he has never once touched my vagina and has only gone down on me twice. I am extremely unsatisfied, before, during and after sex. We arnt allowed to change the position either, it's always the same, missionary. my favorite position is doggy, but I can't even remember the last time i did it. I even bought a karma sutra book for ideas and he said it was a waste of money. I try all different things, sexy underwear, porn, but I always get rejected. I even beg for him to touch me, I have even cried, but he is just so selfish.  And I can't leave him coz we have a daughter together.  I'm at my wits end, I don't know what else I can do. I'm over having to pleasure myself, because he won't do it. I'm even crying now as I write this! I'm 22,?atrractive and I dont want to give up my sex life yet, like I have given up the rest of my life for him (I moved 15hours away from all my family and friends to be with him)  Is there anyway or anything else I can possibly to other then leave him?
