Hi I m 20 years old (male) at the age of 15 ,I started masturbation and still I do. But even now my penis size is very small like flaccid: it s 2.5 -3.0 inch, erected: it s 4.5 -5 inch. It will be even very thin. I don t feel any change in my Shaft and testis size, they only enlarge during erectile. I have not yet got to full extent mustache and beard. Even the pubic hair when for the time it was growing little then I shaved it there after it had grown to some level and there is no further growth thinking that I even haven t shaved it later on. So please suggest me on this ,did my puberty stopped?? Or any delay puberty.?
