any skin lesion in or near the genital area should be evaluated. a description alone does not rule out or accurately diagnose genital herpes but based on what you have posted it seems less likely. it may be folliculitis -- an infection of a hair follicle but without the ability to exam a patient this is only a guess. if you are concerned it is going to take an examination and perhaps a diagnostic test (like a culture) to provide you with the assurance that you deserve.
