Let's Talk About... Anal

Rachel
So yesterday my boyfriend and I had anal sex because I'm on my period. It was amazing, and I loved it. But I have a few questions. This is the second time he and I have done anal. The first time it felt really good but things got, uh... messy. He was totally cool with it and we joked it off and things were good. After that he asked me a few times if we could try again but I always said no because I was nervous about it happening again. Yesterday I finally agreed though. And yesterday was AMAZING with ZERO mess!! I was so happy! So my question is, how do you guys like it, and how do you "prepare" beforehand to limit mess? To my knowledge, I did absolutely nothing different this time than last time. Thanks!!!
