There are a number of poly people on this site that I have the utmost respect for. They are able to do this in a way that completely works, in a way that is quite lovely.
I absolutely love one couple in particular and consider them part of my personal tribe. It does not mean that particular lifestyle is for me.
I think, OP, that you are meaning well... or at least it seems to be... but you are taking something that was negative for you and turning it around to everybody.
It would be akin to my saying:
I urge all women to seriously reconsider getting involved with a man....i have done it twice....the second time, i was convinced he was different.... You know, no matter how great he sounds, jealousy always rears its ugly head.
Do you see how silly it sounds?
Yes, I am a wonton hussy... and still sweet as 3.14
