There is nothing shameful or unnatural about masturbation. Even in the Bible, Onan was condemned for masturbation itself and for interrupted intercourse. On the contrary, periodic masturbation is even useful for several reasons, as I see it. The first is sexual and psychological relief, the second in men, masturbation helps to remove old sperm with low mobility from the genital tract. The next ejaculate will contain fresher semen, which can also increase the chance of conception.
Without masturbation at all, it will be hard and uncomfortable for you, I know from myself, I tried it when I was bothering about religion. In general, ask yourself if you really want to give it up and why, what will it give you. In fact, only you can decide what to do with your body and limit yourself just for the sake of someone's approval, it is wrong.
Addiction is not on masturbation, but on ejaculation ... masturbation is one of the ways to get rid of the semen. They masturbate mainly for two reasons - either there is no woman nearby with whom you can "finish", or there is no desire / time / opportunity to have sex, but you want to "finish".
