My bf is well endowed so he feels the strings often, but when we have very rough sex (my fave kind of course) I have severe crippling cramping for several hours after sometimes. Other than that I absolutely love my mirena- I have had no bad side effects or any complaints until this...
Anyone else have this? Is it just being bumped and irritated or is it something serious?
My guess is what you said, bumped and irritated.
My wife tried several different ones and they all had different characteristics. I could feel the fish line (string?) they had on them with my finger but not with my penis although I think we did have an issue with one type that did something painful to my penis. I do remember her having pain for days after sex when using the inserts, some more than others. We had to be careful not to go in too deep and not hit her cervix at all. That was a long time ago so the details are a little fuzzy. I'm 73 now and she used them for a few years before the pill came out. There were unpleasant side effects to those too. I got snipped at 36 because it seemed everything they had for her was problematic.
