butt sex after a fight....?

We had a fight because I found porn on his phone when we talked and agreed to tell eachother whenever we want it. I cried, he got angry, then of course comes the sex... He "uses porn for new positions", he knows damn well he won't eat me out while I do a handstand :/ I just was dead inside... I just said "do whatever you'd like" and he put it in my ass. It hurt so bad... I know he'll look at porn no matter what I do now...
