When I say death, I'm not talking about when your heart stops beating and your brain dies. I'm talking about the absence of life.
Life, being when you love and trust yourself enough to let your logic, creativity, and passion go free.
To control oneself is destruction of oneself in that it is destruction of your relationship with yourself. Make no mistake; controlling and disciplining yourself is a sleight on an entity that does, functionally, exist. And as it would with a relationship with a person you were intimately close with, it only serves to estrange and distance that person from yourself. Eventually, these acts will create a certain sickness of the soul; I imagine this happens once you truly realize you'll never be free of your own fear and self loathing.
You're talking as if this is some horrendous imprisonment of inner feelings, when in reality, it's the exact opposite. I felt gross doing it, and I'm sure many other participants did as well - the only reason we did it is because it was easier.
Controlling myself doesn't mean miscommunicating, or blocking out communication, or starving myself of food. It means controlling sexually motivated urges and trying to regulate hormonal imbalance in such a way that causes a net, end result of being happier and more content than I am now. You have the perspective that there will be no net result and we should live for the present, ie. furious masturbation and continued sensitization to porn, while I have the perspective that a net result will occur in such a way that we'll all be better people.
