Ongoing anal dispute between SO and me.

Old couple here. This has been a running joke between us for 30 years. Last night I laughingly told him that if he brought it up again I'd ask Reddit (which he despises) for their opinion, so here I am.

Decades ago when we first got together we had anal sex without me prepping and without his wearing a condom - it was all pretty spontaneous obviously. When he pulled out he had a little poo on the end of his pud. I said "Well, aren't you disgusting," ran and got a washcloth to clean him off, and we showered afterward and laughed about it. (Both of us have experienced much, much yuckier things, so it was no big deal.)

*He* says I shat on him, because it's my poop. *I* say he got my poop on *himself*, since "shitting" involves feces leaving the body.

What says Reddit?
