Balanitis? Herpes?

i received unprotected oral sex last wednesday or so. before then it had been a couple of months of nothing sexual whatsoever. around saturday night, i felt my penis tingling and i look and theres a rash of sorts when i pull my foreskin back and its right below the glans on the left side. im scared i got herpes from this interaction. ive been applying clomitrazole twice a day since sunday. clean myself and dry myself in the morning and apply and do the same thing after work. am i overreacting here and maybe it was from a night of not showering after the gym? it doesnt seem to get better since ive applied the cream sunday.

i keep trying to attach a better picture as it goes around the shaft but it keeps saying file is too big. im headed out now to buy some neosporin
