Hey, I turned 14 like 2 months ago, and I'm wondering am I going through puberty. The first time i ejaculated was about 6-8 months ago. Shouldn't other changes to my body happen after my first ejaculation? Well, I have a little bit of hair under my arms. They are short softs hairs, not many of them, but they're there. I have hairs down in my pubic area but there soft and straight. They seem to be increasing in numbers but I'm not really sure. I have grown about 2 inches over the past month. My voice has gotten a little deeper but not that much. My penis is about 5 inches when erected. So, how long after your first ejaculation should you get taller and all the other stuff happen to your body?
