Hi i'm 15 years old amn i have a penis size of around 14-15cm is this normal will it grow anymore and is there a way to speed up/increse the size...
Hi Chanel,
15 cm is 5.9" so you are bigger than average for an adult male - 5.1".
Your penis can grow into your early 20's. No. There is no way to speed up any growth.
Hope it helps.
