I am on my second Mirena, (Love it love it) My ex, could feel it when we had intercourse. He basically tried to explain it to me as almost like a string poking him. But it was never uncomfortable for him, just noticible, and he was so used to it I guess we thought it was no big deal. The bleeding after sex never happened to me, BUT, i'm on my second one now and it happened with this one. I just had my 2nd one put in about 3 months ago. I've actually only had intercourse once since it was placed, this past weekend, and Monday morning, I thought I was going to have a period (which is weird for me, because I've basically only had one period in the past 6 years and that's for hte 2 months I had not IUD in.) But I did not ever actually bleed more than just a little after the sex, so maybe that's normal. I would check on the bleeeing part, feeling it is normal. Guess I could've just said that sentence instead of this long paragraph. LOL>
