Anal Help

WARNING: MIGHT BE TMI

Hey guys so today my boyfriend and I had sex for the first time together. It was also my first time. We wanted to try anal beads (LOVED IT) before doing full blown anal. When he took the beads out they were a little dirty (I was mortified but he didn’t really care). I’m kind of uncomfortable now to do it cause I don’t want it to happen again.

Will something simple like going to the bathroom before hand avoid this? HELP!
