[unknown] ah yes and no, as you may have seen in the showers that all dicks are way different. you might have an acorned knob head, or a mushroom head, maybe a saddle shaped knob. some boys will have either a button mushroomed knob. a cherry tomato shaped knob, so can you see were i am going. all cut boys will have a different knob shape due to how they were cut.
most uncut boys have the same shaped knob due to the foreskin trapping the knob in the skin..
