So im 15 and im a sophomore and i hit puberty about 4 years ago when i was in the 6th grade. I have armpit and ball hair and i am beginning to grow chest hair as well. I haven't noticed any growth in my penis yet ( im am about 2 inches flaccid and a little over 4 inches erect) while all of my friends brag about how their penises are about 6.5 inches erect. When should i be expecting some growth? Should i be worried that i might have a small penis forever?
I don't think you have to worry about it. You're still a teen, and your penis will grow naturally as you grow. It's no need to stress over it.
