I decided to quit masturbation and failed on the very next day. i don't know how to get rid of this addiction?

Why bother: Sex, whether by yourself or with a partner is driven by natural hormonal influences. The only unnatural issues are the myths and taboos various cultures use to shame you for the practice. This like any other activity is best done in moderation & can take you away from other productive pursuits if done to excess. However, I would not lose sleep over the issue or waste any more time worrying.
