I am 15 i have a small penis any ways of helping it grow

Sorry James,we are all different and we grow in different ways.I am 14,15 in dec,mine is 3-4 inch soft and 7 inch hard.But some of my friends,who are 16,have smaller penis and testicles than me.

So you see,If you take your time,and don't worry so much,so will everything be fine before a year has gone.I am pretty sure:-D
