IUD & SEX

Alysen • Been in a relationship for 2 years. Sexually active & on the pill! I have had the ParaGaurd IUD, & the Depo shot.
So, when I got the IUD I waited about a week to have sex because I was afraid it would move (lol). This was about 6 months ago. But almost every time my boyfriend and I have sex he can feel it and it hurts him. Sometimes we even have to stop because it hurts him so bad. Is anyone else going through this?
