I read a similar thread about the topic of Mirena being related to very painful sex, but my problem is a bit...different. I had an IUD put in about 5 months ago. The first two months were more or less bearable with the exception of embarrassing spotting. Now I do not have a period at all or anything that goes along with it! That would be great except for my other problem. BOTH my partner and I experience a significant ammount of pain during sex. I have read about the strings poking men, but that is not it for him. He says it is more like a pinching sensation, as if I were not a virgin. For lack of a better way of putting it, he says that it seems very small and tight. He is not especially large, to the point that it has ever been a problem before and we have been together 3 years. For me, well, I guess to say a "pinching" type pain is about the same. Sometimes I can get past it when the pleasure outweighs the pain, but more often than not, we have to stop. When we are able to get through it, it hurts at least a day afterwards as well. Is anyone else experiencing anything like this? Of course I plan to go see a DR. but I want to be prepared and be able to give specific examples. I know I can't be alone here. Any thoughts would be appreciated.
