I have had the same boyfriend for over 2 years. And we have sex. About a year ago he had sex with someone else. Since then,him and I have had sex many times. but it hasn't been until recently that I have had red burning bumps around my vagina. They sting when I urinate. There are about.8 of them and they arent able to be squeezed. I have no idea what they.are. Any advice?
