Hi doctor I have been masturbating 5 6 times a day and it became my habit neither it increases the size of my penis nor it reduces my body weight. I m 17 year old but according to my age my penis is still small how can i get rid of these problems and the major part is that the upper part of muscle of my penis isn't tear till now I tried a lot to tear it during masturbation but it doesn't get tear why what's the reason behind it and for big penis what could I do
