Hello thanks for asking from Health Care Magic First of all I would like to let you know that masturbation (shaking of penis) is a safe and healthy practice and this is not associated with any loss of potency or loss of fertility. You have complaints of erectile dysfunction and premature ejaculation. I would advise you to consult a psychiatrist for proper treatment if the condition is causing significant distress to your functioning. Medicines like sildenafil, tadalafil are commonly used in erectile dysfunction. Other than this other medicines like Yohimbin also have good roles. For premature ejaculation medicines like dapoxetine are very effective. These are prescription medicines so consult a psychiatrist first before taking these medicines. Herbal medicines like Tantax Forte have good results in erectile dysfunction. Tantax Royal have good results in premature ejaculation. Two tablets twice a day give good results. Hope this helps you, thanks
