I've been having so much fun with this recently.
I've gone to a great poly meetup, met people online, had a date, and kissed a couple of girls.
I love this feeling of freedom and connection. Particularly connection. Somehow having more (romantic or otherwise) connections in my life gives me this great feeling of strength and comfort which felt stunted in a monogamous relationship. Besides feeling stunted, it was constantly under threat - I needed my partner to stay with me because she was my almost sole source of this feeling or sense of support. Now I don't "need" anyone to do anything for me, I've removed the power over me of monopoly. And that feels great.
It's been a lot easier than I expected it to be. I'm taking things one step at a time but at the speed things are moving I can see a blossoming love and/or sex life happening within one or two months. Part of it is because mono relationships need to be perfectly compatible, because you're sharing everything with them. A poly relationship can be less involved if you want it to be without needing to be cold or disconnected. In these cases, there is much less need to filter for a perfect match. So long as you share enough to like and love each other, it doesn't matter if one is a meat eater and the other is a vegan who can't stand meat in their house, or whatever compatibility issues you may have.
Another reason poly feels easier is because there is just less "stuff" to work around. Less ideas, less definitions - sexuality, and romance, are just something simple and wonderful, to be shared. Poly girls seem refreshingly "easy" (in a good way)... easy to connect with, easy to love.
Finally poly is easy because there is no expectation for it to be forever, or for you to fill a role of full-time boyfriend, or for you to love them more than anybody. So a lot of relationships that would be incompatible can be compatible in this framework. Particularly, smaller-scale relationships can work in poly where in a mono framework someone's feelings would likely to get hurt. In poly, there are less ways to set yourself up to get hurt. No rigid expectations means no broken expectations.
