I have 4 inches penis size but I want 7 inches.

Question

Dear Haito, The length of a non-erect penis doesn't consistently predict length when the penis is erect. If your penis is about 13 cm (5 inches) or longer when erect, it's of normal size.
A penis is considered abnormally small only if it measures less than 3 inches (about 7.5 centimetres) when erect, a condition called micro penis.First of fall your penis size is considered in micro penis, the penis is weakened due to more masturbation and due to weakness in the veins of the penis, the penis also becomes smaller. You do massage with olive oil twice a day. Try some vacuum therapy, kegel exercise and jelqing exercise. or you can also take a Ayurvedic treatment for permanent solution of your problem, for more information about treatment please consult us privately on lybrate.

Hi, lybrate user,
Its a hippothetical idea far from the reality, moreover you can enhance  the length of your penis upto 1/2 "massaging mastured oil on your shaft.
Tk, care.
