Eczema Treatment Care

This is more of a guessing game, cause whoevers right, in 2 weeks i get my results, gets the cake.
This may have something to do with sexual activity with a female 3 weeks ago. I didnt wear a rubber and we only went for a few minutes with no ejaculation on my part (im a guy)…..
A week later my symptoms are a burning sensation while peeing, and itching down the INTERNAL shaft… no discoloration, or any discharge. I drink plenty of water every day. I also think this could be a sort of yeast infection or STD.
i’ve also had random yeast infections on my skin… doctor called contact dermatitis i think, dry rashy scaly spots on my skin in 3 places and also 1 on my genitals that hasn’t went away yet. this is not an std…. i’m thinking maybe it could also have an effect
oh and my doctor gave me a vaginal yeast infection pill(2) to take for it…its not ONLY for vaginas i guess cause i’m obviously a dude but maybe this could be a side effect?
I’m not sure when this itchiness started really…
and when i pee it doesnt even burn it moreso feels good cause its itching the itch…
i’ve also drank a bit recently and i havent drank for a while and i’m on the meds xanax.
good luck guessin
