This has to do with paranoia and fear.
Mostly of mentalcels are surrounded by harmful thoughts when they try to approach woman.
but it is a specific state of mind. You do not hear any voice, but your body will force you to believe that approaching a female it's just harmful enough for you to do.
And if you go out and get trough your brain, in mostly cases, your brain will ignite a rush of adrenaline to make you run from the scenario, and if you don't run, you will endure a pain that is left for your entire body. But is a pain 3 times greater than a great kick in the balls.
To control all of this, it takes huge amounts of better decision making, like, live a pure healthy life (when i mean pure, it is in a math scale) and get a specific medical treatment.
