Hey I have iud and whenever my husband and I have sex usually when I am on top afterwards he gets a rash and sometime skin comes off too and bleed.... It is not due to the string cause he don't feel pain during intercourse and one more thing is that I had been having pain just right under my belt button in q small circle like I have been bruised internally it hurted like hell when I bow down or sit plus was having discharge too with itching.... It got better with antibiotic and paracetamol but still I want to know the cause
