Masturbation is part of growing up and even adults do it. You really don't want to repress such a feeling because it'll come back to bite you in the ass later in your life and I tell you it's not going to be a walk in the park. Repressed feelings/sexual urges are what create sexual deviants.My best advice to you is give in and masturbate as often as you feel like. You are not doing anything wrong, bad, immoral, or hideous. You are not crazy for wanting it and you are not a pervert for doing it. You are you and you are a perfectly healthy male growing up. Disregard anything "holy books" have told you, they are the ones who usually spread b.s like that yet promote slavery, rape, incest, killing your own children, hating your own parents.And always remember, as long as what you are doing does not impose on other peoples right and liberties, and as long as it doesn't harm anyone, it's not wrong, bad or immoral. Other people are all that for telling you differently.
