Look at all the things that can go wrong for men. There's the nothing-happening-at-all problem, the too-much-happening-too-soon problem, the dismal-droop-after-a-promising-beginning problem; there's the size-doesn't-matter-except-in-my-case problem, the failing-to-deliver-the-goods problem... and what do women have to worry about? A handful of cellulite? Join the club. A spot of I-wonder-how-I-rank? Ditto.
