answer is BBB.
The presentation is most compatible with recurrent genital herpes simplex virus infection. The limited number of lesions and absence of systemic findings support this diagnosis. Herpes zoster lesions would be more extensive and would involve other areas in a dermatomal distribution. Lesions in patients with syphilis are not painful and do not have a serpiginous border. Group B streptococcal infection would involve the scrotum rather than the penis and only rarely causes lesions.
