About a month ago, I almost had sex with my ex-boyfriend but stopped because I know he is hsv-2 positive. All he did was rub his genitals on my butt but no skin to skin contact or rubbing on my vagina. Two weeks later, I noticed my vagina was itchy, swollen and irritated. I also felt a slight burning sensation near my thighs. There was absolutely no pain, or sores but decided to go to the doctor to check it out because I saw a pimple form. Went to the doctor and she was sure it wasn't herpes. She did a swab test on the pimple and tested for yeast, bv and all other stds. A few days later all tests came back negative. I'm still experiencing slight irritating and itching. Could the herpes test be wrong? (Btw prior to this I had 2 herpes blood tests and all came back negative even after having unprotected sex with my boyfriend who didn't tell me he had the virus) is it possible to have contracted it without sex? Please help. I'm very worried.
