If they are there continually, not showing up and then clearing up, then it's prob what all have said here. They're pimples. Herpes looks like them too sometimes, but they are very sore to the touch and they don't 'pop' easily like pimples. Herpes also flares up (you can feel a tingling before the legions appear) and then clear up after a few days or so and then come back after months or years. Try keeping your groin area dryer , if you can, wear a dress with no panties on during the day, and don't wear any panties or pajama bottoms at night. Also, don't shave, nowhere around your crotch. Do that for 2-3 weeks and if it helps clear it up, you know it's acne or caused by ingrown hairs from shaving.
