Anal sex

I'm having trouble guys!!! Please give me some good advice quick!! My fiance for our anniversary wanted to do something speacial. He wanted to try anal which hurts me cuz I can't take pain. So we work at it he finally gets some in and it's still painful to where I'm crying. He's being selfish and keeps going gets off and I didn't enjoy it even when it wasn't all pain. I'm all for spicing things up but not painfully I know people say it takes time but it's like once he gets stuck on that it's like my vagina is broken he enters it for 2 seconds than wants my ass again I say it hurts n he keeps on. He doesn't like oral n was gonna eat me out last night however he didn't because he was so caught up in anal. I've tried to explain it to him but he is stuck on what he wants!!!what should I do
