About two weeks ago I made a mistake, a sex worker performed oral sex on me with a condom for about 5 minutes. A week later I noticed a bump on the left side on my penis shaft with looks a lot like a pimple or an ingrown hair. But I googled symptoms for genital warts and genital herpes and it said sometimes they start off looking like a pimple so now I am freaking out. I know its hard to know for sure unless I go see the doctor which I will, but I wanted to get some input if this is herpes or just a normal pimple and what are the chances of contracting warts or herpes from a single encounter of oral sex with a condom????
