have you tried anal?

okay so a few days ago my boyfriend and I were having our typical bath together and it usually leads to some sex or oral, and this time we decided after talking about trying something new, that we would try anal and just ass stuff, I had always said that my butt will always be a virgin, and he had always said he never wanted his butt touched, but with eachothers consent and us being so comfortable together we went ahead and tried some stuff, anal hurt a lot for me at first and it still hurts when we do it but my boyfriend enjoys it and I love pleasing him, how can I make it not so painful? Comment please! and also answer the poll(:
