I know, we all do it. I do it. You do it. We all do it. I even enjoy it. I do not, however, enjoy the fact that others do it. Pooping is simply necessary for survival.
For some reason for me personally when I'm dating someone, or I am close with someone, the relationship sours in my mind the second I get any clues that they're pooping. For a long time I was able to ignore it and just think about other things, but my past few relationships have really brought to light how much I hate it.
It was a normal occurrence in my pan-sexual days where I'd go on a few dates (I always preferred women or trans-women/trans-men), and things would be going well. There'd eventually get to be a point where an overnight stay happens and they'd disappear to the bathroom for 7-10 minutes, the smell of Poo-Pourri fresh in the air, they'd walk out feeling proud and refreshed... myself? I felt disgusted. I never would verbalize my feelings as I always preferred to internalize.. I hate that goddamned smell. It's not a pleasant smell at all. It's a "there's poop here" flag, waved high and proud.
In the past this would be a small dip in a sin-wave that would be our budding relationship. I'd get over it, and forget. I'd do things that helped me avoid the fact that my partner poops. Something clicked in my head in recent years and now I constantly think about it. When someone I'm dating tells me he or she wants to go get food I'd hear "Let's go load up with future poop!" When we'd eat something healthier all I could think about is how disgusting this compose-like substance will be as it gets processed through their body likely ending up in my toilet the next day. I'm constantly worried about particles getting on me and my ex even refused to wash her hands after pooping because "she doesn't even touch herself" (this may be part of what asexualized me).
I. Fucking. Hate. That. We. Poop.
