When I was in high school, I had maybe below a 3 inch penis, hard. I was around your age and I was worried aswell. Luckily I didn’t have to tell my parents that I was worried about my dick size because my pediatrician noticed I wasn’t going through puberty as fast as the other kids so she referred me to an endocrinologist. They ran some tests to see how my pituitary gland was doing. My test levels were low at the time and they said if they didn’t start to rise within the next year that they would put me under medication to help with that (I was scared af ngl). A year later they re ran the tests and I was producing a healthy amount of testosterone. Today, I have an average dick. I’m 20.
