Well I have masturbated up to 10 times a day, its just a mental addiction not phisical dependance, in controlling human nature towards sex. The cause of your dick not growing anymore is because you made yourself dependant on masturbating, and mixed with your thoughts that your impotent they seem to get along really well with your dick not standing.
Try something different like having a nice walk, without watching any boobs or asses. Let me tell you I love sex because im sort of social guy but my thing are pull ups.
Theorically speaking, I would guess looking upwards is like watching towards Gods heaven, looking down is like seeing through hell, then actually where are we walking through now?
Simple, none of those, its the earth.
