Any tips on anal?

So my husband is very into anal and it’s hard for me because no matter how gentle he is it always is painful. I want to please him and so in order for me to allow him access I have to be drunk so the pain is dulled. It turns me on that I am turning him on so I am able to orgasm even though it hurts. I try to give him anal once every few months but I would like to be able to do it more often. Does anyone have any advice??
