Puberty and all that lot!?

Ive just turned 16 and (like many men) im worried about the size of my . Its about 6 inches erect and 3 when floppy. I was wondering if effects growth at all? I do this atleast once a day but read somewhere here that staying 'clean' for 6-8 weeks can boost growth? presumably by the excess or hormones or something. Im tall and have got all pubes / broken voice BUT totally bald arms and legs :P so im vague question is...do you think ill get any bigger?
