Hello ladies, Im new here, and thought you could help me with this. My bf is above average, about 8 or 7 and a half inches, and pretty thick, more so towards the head. When we have sex, in certain positions, he hits my cervix, and a few times, this has hurt pretty bad. I need to go on BC, and this is the only option, I cannot have hormones from pills, or patches. My question is, do any of you have IUDs, and does it make sex more painful if the man is big? Thank you for any help.
