Vascular congestion: Testes get gorged with blood during sexual stimulation and that may cause pain. There is no harm and no lasting damage. Masturbation will not cause any ill-effects to your health. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex.
