Didn't you hate it when you were a kid and you were wanking and experimented with the orgasm? Those were the days. You'd stop just before the end to see if you could prolong the pleasure and you'd somehow mess it up so that nothing would come out. You couldn't wank again for a while, because you thought it was bad for you, so you'd spend the next week paralysed by the fear that you'd permanently blocked your penis up. Oh, youth.
