The body can become ennervated by many things including stress, anxiety (this is a major cause of premature ejaculation), poor diet, poor sleep habits, poor diet (eating processing, cooked, animal products such as meat, eggs, dairy, fish), breathing poor air, not exercising, not drinking plenty of pure water, drinking coffee, smoking, taking drugs (including over the counter, herbal and prescription drugs) not meditating. All of these things serve to poison the body and it begins to get symptomatic in various ways (headache, flu, cold, genital complaints etc etc). The body was designed to cleanse and regenerate itself at every moment. When we get out of it's way it will do that perfectly. No drug or therapy can ever cure us. Taking responsibility for our lives and lifestyles is the greatest gift we can give ourselves. Try applying some (if not all) of the suggestions above and see if you're not transformed.
