During adolescence, boys experience a lot of difficulties with their sexuality, which arises under the influence of sex hormones. Often they are onanium, also called masturbation. Onanism also happens in girls, but much less often.
As far as boys are concerned, it is necessary to distinguish between nocturnal bloats (stains) that occur unknowingly as an automatic regulation of the organism and for which the boy is not absolutely responsible, from onanism, made consciously. The boy is also not responsible for dreams with erotic content, because dreams occur alone and we have no influence on them. However, it is not good to give in to erotic or sensual dreams. You should try to overcome it, taking then to some action, which requires some effort of will. Such dreams induce one to masturbate.
Onanism consists in actively discharging sexual tension, which may arise by itself or under the influence of external and internal stimuli (erotic imaginations and dreams).
