This doesn't sound like herpes. It would have been sore to the touch and larger than an ingrown hair. Good luck with the results though.
Thank you for your answer. Just one question can folliculitis spread to areas that are hairless?
With most lesions associated with hairs, you can be confident this problem wasn't a herpes outbreak. Not every folliculitis lesion has a visible hair coming from it. That you found one without an apparent hair doesn't mean anything. In any case, recurrent herpes is uncommon in hair-bearing areas.
If this problem persists or recurs, consider seeing your doctor for professional assessment. But from what you have said, I see no reason to be concerned about genital herpes.
I hope this has helped. Take care.
