Is that normal??

To all my anal loving friends, I’ve done anal before, masturbated anal before etc. I’ve never had any serious issues. Today I was masturbating in the shower (anal) and once I was done it felt wet. Not because of the water though lol. I went to the bathroom and it was like I pooped liquid. It wasn’t much but it was like yellowish clear. What was that? I know it’s gross but I’m really confused and a little concerned.
