Jerkometer - App That Tracks Masturbation [Serious]

This is completely serious and I hope I'm not giving away a million dollar idea. But is there an app out there that tracks the amount of "strokes" doing a time of personal pleasure?

It'd be just like the pedometer but with jerks.

You could track your history, get special badges for reaching a goal or even breaking defined records. You could also have options where you can track each "session" with whether or not you were watching porn, location or anything else.

Just an idea...
