Anal aftermath

So I’ve come to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> because I’ve always wondered and cannot find an answer anywhere on the internet.

Every single time my partner finishes inside my butt when we do anal the next day I have runny poos all day. Like not rlly bad like watery. Like I legit have been toilet today 3 times and if I was to fart I would shit in my pants basically. Haha this is such a weird question I’m just so curious.

Is there a reason this happens does his sperm do something. It’s not annoying or painful just random.
