I have a test scheduled for Monday. I'm very stupid and waited a month until after the experience to even look into testing.

Got unprotected oral last month. About a week or two after my penis got really dry and itchy. That resolved itself with some hydrocortisone but there's a very strange symptom I've undergone that's inexplicable. When I rub any kind of solution onto my penis, antifungal cream, lotion or any other moisturizer, I feel a burning sensation that will only last as long as I rub it.

No outwardly obvious symptoms like burning when I pee, discharge, warts, etc. but I know these STIs can be asymptomatic.

What does this sound like?

Also if my partner last month was carrying something and she gave me oral sex, would it be possible for whatever she was carrying to travel from my penis to my mouth?
