toilet paper on the crack: how my friend with bennie made me feel like shit about it

So, tonight my friend with benefits and I hooked up, and afterwards, I got a message from him saying "wipe your ass more darling. That's why the car stank after it." I had no idea how to respond, and I went home immediately!! As soon as I got home, I realized that it wasn't shit stains or something else he was disgusted by... it was the toilet paper that was left behind from wiping earlier that day (I don't shave regularly). Now, keep in mind I didn't have any time to prep or wash anything off or whatever, but I guess my question is... do any of you have experiences like this? Or do any of you have this happen? PLEASE let me know😭😭
