About a month ago i recieved unprotected oral sex but it was only for about 5 min maybe 6 minutes tops. The next day or 2 i started experiencing discomfort on my left testical and a slight sting on the lips of my penis. But i haven't gotten any cold sores, havent had pain urinating, nor the genital bumps on my penis. However i have been getting a rash as of a few days ago. Ive been itchy from my chest, my buttocks, and my back. If its herpes i would like to know information about it.
