I got a mirena IUD about 1.5 years ago. My sexual desire has been normal if not even more than normal. In the past three months, I stopped climaxing. I'm very attracted to my partner. I explained it to him like I'm on a roller coaster with the peak cut off the top. I experience the excitement of building to the orgasm, but suddenly the ride is just over without feeling that exciting drop. Could this be due to the IUD or is it more of a psychological thing?
