They are offered by the Human Awareness Institute in a variety of locations around the world, but near the Bay Area in California is the nexus. Also, note that it is not called the "Sex, Sex, and Sex Workshop". These people do an incredibly good job of walking their talk, and it is Sex, Love and Intimacy.
Try doing fun things in real-life. For example, I got into playing Ultimate Frisbee, rock climbing, sky diving, and other sports I was excited about. Being happy and full of energy, in contrast to being depressed about my rotten love life made a huge difference in my attractiveness to women.
Expand your horizons beyond geekettes. There are relatively few *available* hot, geeky girls.
Try being generous -- offer to take a woman out to dinner and quietly pick up the check.
Be willing to date a woman who is less young or less thin than you thought you were looking for. I've had some amazing, wonderful and long-lasting relationships with women who I wouldn't have thought I'd have fallen in love with.
Dancing is also a good one. I've been taking salsa lessons, and there are several good looking girls for each guy who comes to class! :-)
