BM after a guy ejaculates

I’m grossed out even asking but my friend called me today and said she had sex with this guy she’s been seeing for awhile and they haven’t had sex in a couple weeks but this morning they did and when they were finished he wiped himself off and then gave her the same towel to wipe herself and she said as she was wiping she smelled Shit and looked down at the towel and there was literal shit on the towel and she was like wtf is this and he was like oh that’s just an old stain and she threw the towel on the floor and ran to the bathroom and had shit on her leg where she wiped. I have NEVER in my life experienced anything like that so wanted to bring the question here

She was not the one who shit herself 😂 she was so grossed out and changed and said goodbye and left 🤣🤣 could he have shit hjmself when he came maybe? I said maybe he was so relaxed and it’s been awhile since they had sex? They have been dating 8 months that’s never happened before. Sorry for the gross image but I had to come here and ask lmao
