Hi Jai,
Your penis length is fine for a 13 year old. There is a lot of variation when it isn't erect anyways but 4" is pushing it. For an ADULT the average length of an ERECT penis is 5 - 5 1/2".
Just because you are 13 it doesn't mean that you can ejaculate. It'll happen when your body is ready. Do you have signs of being in puberty? Any pubic hair for example?
Everyone develops at different rates/times. Don't compare yourself to others.
Hang in there, good luck.
hi, i'm also 13 and not much bigger than you. if that makes you feel anymore normal? :)
and about the not being able to ejaculate, i couldn't at first either and then i started shooting clear stuff before i could full on ejaculate.
i'm also sending you a private message. if you want to talk about it more, please reply!
Just a quick note about the private messaging:
You do NOT know who you are talking to. If you have something to share then put it out in the public forums. What are you hiding by going private? Someone else may have the same questions.
Be careful. Do not give your name, address, or your personal email.
