Rash by genitalia

hello everyone,
i was doing yoga today and felt an itch by my genitalia from the movements I was doing and decided to check out what it was from. as you will be able to see in the photos, there is red irritation by the lower part of my vagina, some dry/rash skin surrounding that. Right outside the left side of my lower labia, there are a few bumps/rough skin right where the itching took place. it does not hurt at all and only itches with fabric rubbing against it. i have no other symptoms either.
few questions:

  1. do the bumps look like herpes? i dont have reason to believe it is but an slightly concerned because i have never noticed something like this.
  2. what does this rash that reaches further out look like?
