6 inches is good size penis.
You stuck with what your got unless you want surgery.
pills dont work.
they may say they have proof they work but ultimately this is lies, what you may gain is your penis being plumped up a bit and you think, wow, its bigger, then you keep taking pills and nothing happens. And then it goes down again
it can harm you, taking extra chemicals and crap into your body and pills that claim to make you bigger are just bollocks, marketing advertisers are just playing on mans biggest insecurity, their penis.
You have 6 inches, if you've got a nice girth your gunna please several women or men.
Dont worry. Your 16 aswell, you'll stop growing at rougly 24.
Dont waste your money.
