Viagra, not natural, yup. BUT, very helpful to relationships, to self-esteem, to relieve frustrations in performance, or even as a recreational drug. It is worth having around, if you need it, or if you don't.
Prostrate produces and regulates the flow of semen. It controls the release of urine. It keeps a nudist from dripping all over the place, or being incontinent and having to wear coverings. Very very very.....
