Dear Welcome to HCM We understand your concerns I went through your details. I suggest you not to worry much. Penis length is not at all related to masturbation practice. It is a wrong concent. In fact penile strength increases when you masturbate in moderation. Masturbation once per day upto the age of 25 could be considered healthy. Penile length in unerect position could always be less than 2 inch for almost all male across the world. Also age shrinks the skin around the penis and scortum and we feel the length had decreased. Erect penis size of 2 inches is enough to satisfy a lady. Now is your time to concentrate on studies and career and not to worry about sexual organs and sex.
