OMG

A question was posed today and I don't know the answer. You'd think after reading all four books five times through there would not be many Twilight questions I can't answer. But I am stumped. Maybe you aren't. Follow along, please.

You've been converted to full vampire status. As the poison converted your body from a mortal to an immortal state, your blood thickened, your organs hardened and cooled. Eventually your heart stopped beating and the conversion was complete.

Even if something were to break the surface of your perfectly impervious skin, you would would not bleed. No blood pumps through your veins. Now granted, I've spent far more of my life beneath the sheets with women than I have with men, but if I recall my male anatomy correctly it takes some serious blood pooling to create that male magic known as an erection.

So how the hell does Edward get wood for Bella?
