IUD HELP

Ashley
Hello ladies! In a few weeks I will be getting my first IUD and I must admit that I am very nervous. I have obviously done my research but I have been told some horrible things about getting an IUD. I have heard that if my partner has a decent sized penis that it will be painful during intercourse and that it easily gets embedded into your uterus. Ladies please tell me your experiences, good and bad. And just incase it matters I have never been pregnant. Thank you so much!
