Hello doctor I want to know about penis gland /tip of penis. I am uncircumcised I vividly remember that till last year My penis gland is very sensitive that I cannot touch my head of penis after retract foreskin. But now seeing it today sensitiveness area of penis gland decreases day by day I can touch more area of gland and feel nothing. I want to also mention that there is always pain / current type sensation in my penis in gland and whole penis I do a lot of masturbation in childhood but last 4 years I have reduced habit of masturbation. I am very afraid please suggest something.
