“Everyone has their own reason, but your “why” should be specific to you and wholly dependent on you. This means you should want to explore for a more fundamental reason than just having a fun time,”
This is a pretty good introduction overall, but why shouldn’t wanting to have fun be a good reason to try non-monogamy? Isn’t dating supposed to be fun?
Maybe they meant that you would do well to seek deep meaningful relationships?
I would argue that there is nothing wrong with having fun, with the stipulation that a deeper long term connection can be very much more rewarding. Like, it’s a good place to start, and without it, you might have a less rewarding relationship.
