I agree - if the person was a virgin, the only form of herpes you could get would be genital hsv1, if the person had oral hsv1 and performed oral sex on you.
I'd go with the pantyhose-irritation theory too.

if you shave your area and wear a thong or underwear with a tight elastic, it will definitely cause irritation from razor burn and chafing, if you've only had sex with a virgin, i doubt you have herpes.. sometimes if you shave completely down there, you could be a little tender the next day.. it sounds like razor burn to me, and if u dont shave, it could just be irritation from your underwear..
