Does this look like a herpes sore? Please HELP!

so a few years back i burnt myself pretty badly with some nair hair removal cream. its healed up pretty good now but my skin has healed shades darker and just at the opening of my vagina the skin is very thin so its easy to tear and with the slightest rub of my underwear or any friction (especially during sex) it can rub my skin off leaving sores. this happens alot and i treat the sore with sudocreme. but recently i learned of a rumour that had been going around ages ago of one of my most recent unprotected partner having herpes. i only slept with him once and i did not see no lesions/sores - anything abnormal with his penis. it wasnt intimate as he finished very (VERY) fast and i had no symptoms after sleeping with him. i also went to the clinic and was seen a few weeks after sleeping with him and did a full screening (bloods , swab , cervical swab the LOT) and everything came back all clear. today i woke up and there is a sore right on my thin skin where the bad burns happened (like i said this always happens and it takes a little sudocreme and fresh air for the skin to heal , its always in the same place right at the opening of my vagina as the skin is very thin there now) which looks exactly like my skin rubbed off again due to me wearing tight clothes , however because i have recently learned of this rumour it has unsettled me. i havent been able to get in contact with the partner as of yet so he can confirm or deny the rumour. apparently he gave the herpes to his ex gf ( this could all be made up as they didnt end on good terms) i really hope i dont have herpes i wont be able to live with myself. PLEASE HELP
