Is it any problem if i masturbate 3 times continuously. i am 18yrs old. i just want to stop this, cuz i can't concentrate towards study. ?

Do all in moderation: Normal men, women, boys, and girls masturbate (it's universal). It isn't harmful, as the body goes through similar effects during regular sex with a partner (but too much of anything may become a problem). Masturbation does not stunt height, cause hair loss or gray hair, make you weak, create heart problems, lower testosterone, affect virginity, lower fertility, change your weight, or damage eyes.
