Does anyone else feel their IUD?

Hi ladies. I got the Kyleena IUD about 4 months ago and more often than not both me and my boyfriend feel it during sex. It is not just a slight discomfort, it actually cuts the tip of his penis to the point where it bleeds. For me, I get a sharp pain in my uterus (similar to the pain felt when it was inserted). I just want to know if this is normal and if anyone else experiences this. Thanks!
