Anal Advice.. HELP! ( kindaish TMI)

Katlyn
So my fiancé really loves anal and I HATE It... I just don't like it because it's painful and doesn't really give me any pleasure. We have tried butt plugs, special lives, different positions practically everything we can think of and it still just hurts me. The only time I can let him actually do it is when I am orgasming and as soon as it stops he has to stop bacause it hurts again. I try to relax and let him but I can't seem to get my body to just relax and take it slow. Any advice as to make it better ?
