Hey man you don't be scared you're only 16. I was 5.5inches when i was 16. At 25 i reache 7inches. To be truthful i was glad but i keep reminding myself that your brain is the largest sex organ!! Once you know how to use what you have you'll "ace the test!". Big penis and no brain is definitely not cool!! Remember you're only 16 you have alot of years ahead don't be too hurry .
