that's a lot of words to basically say that it's hard to have more than one deeply personal relationship which is prima facie true. it is indeed simpler than that. i respect your authoriteh as a wise elder. don't jerk off at me about it because I'm not the one who needs to hear it with that aside my anecdata from my more limited set of experience is that polyamory is a fancy word for roommates that sleep in a big bed and that it's a thing that fags do to afford to live in the big city. i'm neutral at best on it and it seems like it just amplifies the shitty behavior of a shitty relationship x (number of people) x (time). i have never met anybody in a legit poly relationship who isn't either 1. dirt poor 2. trans 3. being actively groomed or all 3. people who dip their toes into it get burned. you need to hard commit and trust the fuck out of everybody involved for it to even have a chance and personally i haven't seen it having sex with other people while being in a relationship is rolling the dice on whether somebody's gonna catch feelings and as time increases the probability of that approaches 100% unless you're bob and jan at the swingers party tag yourself and post in the comments what your postcoital physiological response is: mine is typically being asked to leave the restaurant
