Suggest Remedy For Blisters In The Genital Region

I had extremely minimal unprotected "sex". More like, the guy took it way too far and I made it stop before anything *really* happened. Well 5 days later I started having hot flashes and feeling extremely weak and a little lost. Then I developed blisters on the genital region and discovered at first a very chunky white discharge which smelled like 'Burnt bread' and then that changed to darker watery yellow/brown tinted discharge. My mouth is also extremely dry every time I wake up. What could this be? [Dr. tested for Yeast Infection, Gonorrhea, and Chlamydia and they all came back negative] Help!
