My bf insist on having sex and will not wear a condom ever. I have to get a pelvic exam and the night before he will cum in me three or four times. So I douche to clean up and my Dr tells me that is wrong. he wants me to not have the sex the night before. But my bf will not go a nice with out it. So the Dr gave me some condoms and told him to use them.
He will not and keeps messing up my exam and test.

How do I make him stop this?
