There is already the article Religious views on masturbation, you might ponder that Wikipedia is not all that one-sided. It's just that in health matters apply WP:RSMED and WP:MEDASSESS, not religious or popular opinion. We don't pander to popular opinion, we follow the medical consensus and the scientific consensus in psychology. Unless you have mainstream academic sources showing that MDs and psychologists don't consensually agree that masturbation is a healthy and normal habit, you are not entitled to modify the article according to your musings. Nobody denied that people feel shame about masturbating, but medically and psychologically seen masturbation is healthy and perfectly normal. It's just not something one does in public or brags about. You might ponder that not only sex therapists (which you more or less called them perverts) agree on this, but MDs in general and psychologists in general (although consensus isn't unanimity, so there may be some fringe MDs and psychologists who hold weird views about masturbation). E.g. I have searched the whole DSM-IV-TR for the keyword masturbation and nowhere is it considered a disease. It is considered problematic only when done in public, overtly or when it leads to other health problems, such as encopresis (when produced by anal masturbation). It is also mentioned in connection with the Chinese superstitious belief that loss of semen produces the shenkui syndrome.
