Masturbation is Manual stimulation of the genitalia leading to orgasm. Though people have different beliefs about it. However, medically it is normal to masturbate. How many numbers of time? It is up to you. However, if you do it in more numbers, your body will definitely be affected. You will feel pain in legs and back.
In my opinion, one should not do hand practice unless he feels that he doesn't has any other way out. You can do it once in a week or month.
