I had a Pap smear a half year ago. I didn’t have an STI. Since then, I’ve had one sexual partner. I dated a man in his fifties, quite a bit older than me, who ended up having a lot of trouble getting it up and so we didn’t have much piv sex. When we did, it was always with a condom. I just had a new Pap smear and it came back positive for an STI. I’m completely floored. How is this possible?
