Hi! regarding Masturbation
by the adolescents , i would like to add that it is being practiced to get sexual pleasure. So even if one does not masturbate he is not going to loose any thing rather his erections will occur while he is in sleep , dreaming and ejeculation will occur. Many young patients come with the complaints of feeling of weakness as there has been ejeculations every night in the last week, which they call as "Night fall". so if you are very particular for your son to get the sexual pleasure you can do arrangements otherwise it is o.k.
