I'd be interested in seeing this device have it's data outputted to a graph to see what kind of pressures someone finds most agreeable. That way you don't have to fiddle with every device after that. Also, as someone mentioned, it would be a great way to create a preset based on your mood. The data could be correlated on your emotional state, by entering a standard 0 unhappy 10 extremely happy. And then monitoring though a period of maybe six months so you know when your libido is the highest. As a male, I'd love to have my biorhythms matched to a device that would basically "know" my preference based on the time of day / year. I suffer from SAD and masturbation tends to help. Not to mention it would be a kewl hack to have a chart showing you the times your most likely to be sexually aroused so you can plan around it with your significant other.
