First time Anal

So last night me and my boyfriend had anal sex for the first time. We’ve tried before to have anal sex but I couldn’t deal with the pain and jus clenched up, even with lube. But last night I was feeling veryyyy frisky and wanted to do something new. We were having sex and he started to eat me out, and lick my ass, and he started to finger my butt. I had already cum at this point and I wanted more. From there he asked if we could try doing it again and I was all for it. I used Vaseline to lube myself up, and I was ready. It hurt a little but it was going a lot better than it usually did. He was so gentle and kind about it. Finally he was all the way in and I felt like I had to shit so bad but then it felt so good. it was an odd sensation between pain and pleasure, once i got used to it, it was such a good feeling, and feeling him cum inside my ass was amazing. Happy to pop the booty cheery
