On one side, we got the masturbation addicts, people who just cannot stop masturbating for more than a few hour. These kind of people probably have their hand on their shaft as they are reading this, and they would rather die than to accept the idea that masturbation can be detrimental to their anxiety cure.
On the other side, we got the celibates, those that believe that any masturbation will result as direct increase to their anxiety, so try to completely remove any sexual desires as possible. Their belief is the longer they can abstain from masturbation, the better. They most likely believe in the loaded gun theory.
In the middle, we got the moderates, the minority, that believe that once in a while masturbation is ok. Too much can be harmful to their anxiety cure, as well as the polar opposite. They are usually more apt at seeing the pros and cons of scientific fact and theories, and have a more open view around them compared to the narrow minded view of the extremists.
Then there is those group of people who absolutely refuse to be classified into a category, but we can imagine them floating in space because their opinions don't matter, its safe to ignore them.
