KCC, I feel the same way you are as I am in the same situation. My boyfriend is poly and he introduced me to it when I was failing in my marriage last year about this same time.
My boyfriend gave me this site this morning to review and I am glad to have found someone who feels the same as me.
I also feel for you with PCOS. I was diagnosed with PCOS about 2 years ago. Being on the regime for that condition, I was able to have a beautiful baby girl 2 months ago. It is possible to conceive and I hope you are able to.
I found most of the replies in the message as helpful, but it seems with differences lately, that my boyfriend and I will be splitting up. He was patient in waiting for me during my pregnancy, but that did not give me time to experience what I needed to.
Good luck to you.
