Soo, my boyfriend and I haven’t had sex for over

Patient: Soo, my boyfriend and I haven’t had sex for over 2 weeks except tonight, well the past 2 days or so the inside of my vagina has been itchy, I take showers every other day or so, and after we had sex tonight it burned to pee. I couldn’t think of anything else except a UTI but I don’t understand the itchy part. Any idea?

Symptoms: Itching, burning pee.

Doctor:
