im 22 and i just started experiencing this recently. but i seem to be getting these red bumps around my genital region that resenble pimples. but no head. they dont cluster like herpes. and i dont notice them until i look down. they appear randomly.. ive actually "popped" on and it looks the same as a hardened white head. but bigger than what you would find on your face. about 1/3 the size of a grain of rice
