Playgirl and adult game developer Artmunk (Lovechess, The Virtual Express) teamed up to release The Virtual Encyclopedia of Sex, a 3D PC/Mac game that promises "the latest insights and researched sexual techniques from authorities like Dr. Alan Manevitz and sexologist Jayme Waxman."

The Virtual Encyclopedia of Sex allows you to customize characters (hair styles, tattoos, pubic hair, etc.), direct the in-game camera to zoom in and get the perfect angle, and control your couple to completion in a variety of sexual positions. The game even has achievements that reward you with special clothes and advanced positions.

For those with limited experience in the ways of love, the game offers a sex guide and tutorial to get you started, which will probably offer more useful advice than the implausible second-hand stories your best friend in middle school relayed to you about his older brother's courtships.

You can see some very not-safe-for-work screenshots for The Virtual Encyclopedia of Sex and watch a trailer at Artmunk Games. The game is available to purchase for $29.99.
