Firstly go across to any laboratory & get a herpes IgG
& IgM done before speculating whether herpes can or cannot cause such symptoms.
To answer all your questions in a nut-shell, yes herpes can present with all these symptoms. The discharge need not necessarily be herpes & may be a secondary infection both admixed bacterial & viral infection. Since it was an unprotected exposure, any infection may have come on board piggy-backing on the other. Fungal infections are top of the list eg candidiasis
However, you may want to do a battery of tests including an Elisa
for HIV for completion sake.
Once the lab tests get in, you will have a clearer picture. Do go across to a dermatologist
nearest you. Practice safe sex in the future please. Good Luck!
