Most people know what they want, they don’t need to do a deep dive to know if they do or do not want to shag around. Some people are repulsed by the thought of it, they love sex, aren’t ‘vanilla’ with a partner but just consider it deeply intimate and bonding, sacred, and to be protected with faithfulness, and wouldn’t want to do that with just anyone, or go off with others. Polygamists always state “one person can’t give you everything”- they haven’t met the one person that means everything to them and fulfils them. There’s nothing wrong with being alone- you cause less damage to others that way.
Some aren’t repulsed by the thought of sleeping with others and get attractions to other people- but they are repulsed by acting on it, and some like yourself consider it an intrinsic part of who you are, and seek out a partner who thinks the same. You can’t actually know that you wouldn’t want to be monogamous if you met the right person. I didn’t go ahead with the relationship with that guy because his obsessive conversation about polygamous ways of being and fancying others made me see that despite his love declarations and how much he wanted me-it was a shallow form of wanting, and that I wasn’t his person who would fulfil him totally. At least you are with someone of the same mindset and not cheating on someone, if this is really the best you envision a relationship being.
Shagging around or coming to the conclusion that you want to shag around is not “doing the work”, again, it is not enlightenment, it is something that some people want even when in a relationship, but they know it doesn’t serve the relationship, only themselves. Others as I’ve said, couldn’t think of anything more repulsive and foreign to them than thinking of anyone else the way they think of their lover.
The poly couple I knew, once the cat was out of the bag, said all this enlightenment stuff and how it makes them stronger blah de blah, they go home to each other etc, there’s so much more to a relationship than sex etc., but she was constantly pissed trying to deal with it, and he was coming on to all her friends, they are in their 50s now, and he shacked up with a 25 year old about 5 years ago, which was inevitable. According to a friend they are monogamous, which is no surprise to me as she clearly does it for him more than his ex did
