I'm 17 years old and puberty for me is very delayed. So far i only have pubic hair, ejaculation, a little arm pit hair, teste growth. I look way younger than i should and my body figure is that of a child's. My voice still is the same as childhood and hasnt even cracked yet. I haven't had any pubertal changes in the past year. I'm afraid that puberty for me just stopped somehow. What could be the problem here?
