i m 24 yrs old. i had masturbated from 15 to 24 age. Now i stopped it. But, now after every ejaculation , nightfall, i feel pain in shoulders, knees, palms of hand & feet.If i see any hot scene for a while, i ejaculate quickly in little time involuntarily.Is this sign of PE. Besides, weakness, fatigue also . I want to get rid of it. I want to be normal so that i can marry safely after getting well.Kindly advise the proper medicine for it.
