Easier said than done. I don't think I've managed to go more than three days wank free since I was 13. When I try, I begin getting aggressively flirty with people around day two, and starting picking up weird habits by day 3...like blowing things up in my back yard.
It makes me think I beat off not for the pleasure or the habit, but because it keeps my darker impulses at bay. I'm serious. If I were to go 4 days, I'm willing to bet all of you here would be enslaved to me, toiling away in my salt mines for my own personal profit.
...which I'm sure thewitt would appreciate, because it'd mean you've all got jobs. And I wouldn't tolerate unions. Oh hell no. Not in my salt mines.
