When will my penis grow?

Last updated on August 28, 2020


I’m 13, 105 pounds, 5 feet 6 inches. I have a lot of pubic hair, a little armpit hair, no facial hair, and no chest hair. I have some leg hair. My testicles hang down sometimes but not always. My penis is usually 2 inches not hard and about 3.5-4 hard. My voice hasn’t deepened that much. I’m really active, and I don’t eat much junk food. I can ejaculate, but it is clear, white, sticky, and doesn’t shoot out.

When will my penis grow and what stage of growing am I in?


The reason I wrote the Tanner Stage Calculator is that questions like yours are common and almost always unintentionally leave out some information. Please realize that I can only go by the information you tell me. I can’t see you and can’t verify that your description is accurate or complete. This is not to say you are telling me the best that you know, it is just that most descriptions are imprecise by nature. For example, exactly what is “a lot of pubic hair” or how is a fluid clear and white at the same time? I’m not asking for an answer; I’m just illustrating the difficulty on my end.

Your penis has been growing. Little boys don’t get 4 inch erections. It will probably continue to grow for a while, but that growth isn’t rapid.

My guess is that you are in stage three. You probably are in your growth spurt and during this time your penis will continue to lengthen.
