im 18 and have been in the modelling business for only a few days now but theres a problem? on my first day of photo shoot, my agent said he needed to see my penis for a "size check" whatever that means? I assumed he was talking about the bulge for an underwear line so i showed him my junk anyways but ive never heard of this before? i dont feel scared or feel vulnerable but just want to know? is it normal?
