Condoms.

I have a boyfriend of 3 years. We have sex occasionally or when I’m off work because I have been working two jobs for school. We always use condoms because it safe thing to do. I had severe back pain thought it was a uti. But i came positive for a sti. I don’t understand why I would get one if we used protection for anal vaginal and oral. How is this possible. He’s in denial And won’t get tested. Overall I’m sick of this. He is the one I lost my virginity and the only person I slept with.

We argued and said I was born with it. 😒

Edit it’s Chlamydia And I don’t like oral performed on me so no.
