Hi Satheesh, Thanks for posting in HCM. I understand your concern. Masturbation is the sexual stimulation of one s own genitals for sexual arousal or other sexual pleasure, usually to the point of orgasm. It is a natural phenomenon. It releases your sexual pressure by yourself. Thus it eases your sexual tension so improve your health. Since it is a physical act, it may cause some amount of physical exhaustion and experiencing pain in the hands and legs. This can be overcome by taking analgesic medication like Ibuprofen. Your body produces semen that can not be stored unlimited in the body so nature try to ejaculate it by night fall or induces the person to masturbate. You don t have to worry as it will not cause any harm to the body and will not affect sex life after marriage. Hope the information provided would be helpful. All the best.
