Maybe when it gets so big it won't fit in your Speedos. It grows between 14 and 16. Like any other part of the body a little exercise helps.

Worry only if it is less than 3 inches and that too after 18 years of age. Regards.

Never worry about it. Your a kid live life, dream, find hobbies. Your overthinking and you wont even know what your working with until after you are out of puberty prolly around 20 it stops growing..
