It’s taken me a while to stop slut-shaming myself, but I’m working on it (and you can too).
There is an obligation to put your spouse above yourself. Polyamory, for us, fills that obligation rather nicely.
I’m marrying someone who thinks it’s hot when I sleep with other people.
I’m monogamous, and even I think it’s weird.
Open marriage has its challenges, but personal time outside of being a parent is a great reward.
