I was at Borders yesterday and saw this book called Bonk.
Looks interesting and I flipped through the pages. An interesting paragraph on the the erect penis caught my eye.
According to a Taiwanese doctor who specialises in penile implants, when the penis is erect the most common direction is to the left. This was followed by downwards, left and finally upwards. Sort of like anti-clockwise.
Indeed, this is a startling observation for me. It basically contradicts what I have observed.
From my limited *ahem* experience and the porn that I watched, I have the impression that facing north is the most common one. Thus far, I have only seen one that points left and the rest all point upward.
Anyone else care to share their empirical observations? ;p
