Hi im 14 and i have some hair on my armpits and pubic hairs plus alittle mustache but it dosent seem that my penis is growing at all and i get self conscious while changing after gym.
Not everything happens at once and we all develop at different rates/times.
How big is your penis?
Are you comparing flaccid penises? There is a wide variation in size. Some of the "small guys" are growers while the "big guys" are just show-ers.
Erect, most guys are about the same size.
You are developing normally.
Hope it helps.
