My age 20, height 5.8 , weight 72k, male Hello doctor ... I need your valuable advice, here is my problem, I did masturbation for about 3 years... Now am fine but my penis looks small... I think that happens because of my habit... And am in lack of self confidence in coitus life... It will affect my coitus life? Prefer me some ideas for enlargement of penis.... I feel happy if it is a detailed advice....
