My partner of 8 years finally told me that I smell like poop during sex and I should close my butthole. I didn’t even know it was open?

I shower daily (scrub all my nether regions), and have a regular poo schedule. He said that after having a child, it smells like 💩 every time we have sex rather than pre-baby when it happened occasionally.

So, has this happened to anyone else or should I call my OBGYN?
