I'm 18 and my bf and I have probably been sexually active for almost two years. We both lost our virginities together and my doctor knows I'm sexually active but I've never been tested because my parents can't see it or know from insurance. I have a yearly birth control appointment tomorrow and I know she's going to ask if I want to be tested. What should I do if I'm almost positive my bed hasn't had sex with anyone else and I know I haven't? Even though condoms don't protect against stds and STIs we've used them every time except two or three times. Thoughts?
