HiI have a mirena coil.  Is it possible my partners penis could rub on the threads. I know the threads can be felt when I have an examination. He has a blister where the foreskin joins. It hasnt been a problem before, maybe it was the change of position.
Hallow Dear, Though the threads of coil are coming out through the cervical opening, they are not loose hanging. They are flush with the vaginal walls. Hence, they cannot hurt the penis during intercourse. As it is after insertion, we cut the threads short, just sufficient to feel them and hold them while removal. The blister at the foreskin joint with the glans may be due to some other cause. Please report to STI and Skin specialist or a Urologist for opinion. IRENA need not be blamed. I hope this clarifies the confusion.
