Hello, I'm in a monogamous relationship and we have unprotected sex. We've been under treatment with Pidotimod for a month, because of some pink wartlike bumps on genitals. We've just got a few more days to go. Last night I gave him oral sex, he took a shower in the morning, and tonight he's got an awful red rash all along his shaft, and it's itchy. I've been a bit itchy too, with vaginal discharge. What can it be?
