hi, im 25 yrs old, 6'4" and my penis flaccid is only between 1-2 inches and majority of the time my testicles tend to hang lower than my penis. Is this normal? Also erect my penis is only 5" in length. Is this normal? Everything else on my body is huge except where it matters the most, i.e my penis. Is there something wrong with me or do I have some growth hormone deficiency? Is there any enlargement methods I can do?
