Hiya, My heart goes out to you, I have endometriosis and apart from painful periods from the age of 12, my first real encounter started at 21 with EXTREME pain during intercourse. I suffered for at least a year before I was brave enough to go to my doctor, who was a complete B***H. Anyway to cut a VERY long story short, many DRs and 2 years later I was diagnosed with endo. I don't know much about PCOS but the endo felt like a hot knife being insterted it was a nightmare. I had surgery (lap) and had severe endo throughout including my vagina. Once this was removed the problem went away, it can still be painful at times but nothing like it had previously been, but unfortunately mentally the pain is still there and this causes friction with my husband. I know exactly what you feel regarding the guilt and the pressure, I'm lucky my husband has been with me for 18years (since we were 17) and is wonderful but I felt like I was letting him down. I don't know how your conditions have been diagnosed as I'm not familiar with them but a lap to eliminate the possibility of endo might be your next step? I sincerely hope that you get some answers and relief soon. Just know that your not alone.
