i am 37 and had the mirena for about 2 years now. i absolutely love it. my two daughters also have the mirena. it was very painful going in but that was it. i no longer have any periods which was the reason i had it put in the first place. my daughters love it too. as for the sex drive when i had my last child 8 years ago i lost all my sex drive, it was like a chore to me, since having my mirena i cant seem to get enough.WOW!!!!!!!! please give it a chance it will probably get better
