Hi i was just diagnosed today. Thats what my first sore looked like except closer to the perineum. Now having a full blown outbreak im not a medical professional but i would get tested asap so you can start antivirals as quickly as you can to avoid unnecessary pain. ive been suffering from over a week. good luck 
so you have genital herpes?
how long did it take for tests to come back?
the doctor took one look at my vag and said it was herpes. but i also have a lot of sores now after theyve spread. genital. not sure which type im assuming hsv-2 or both 1 and 2. the doctor said my results would be back within a week. ive also had a sore throat and swollen lymphnodes in my groin. maybe check yours
does it burn when you pee???
