Orgasm Detection & Erotic Sexual denial

Erotic sexual denial, also known as orgasm denial, is a sexual practice in which a heightened state of sexual arousal is maintained for an extended length of time without orgasm, and is commonly practiced in association with BDSM and sexual bondage. Erotic sexual denial can be another name for or variant of orgasm control. Erotic sexual denial is a form of sex play.

Can that be Geeky?

Reading the Document “8–13 Hz Fluctuations in Rectal Pressure Are an Objective Marker of Clitorally-Induced Orgasm in Women” (Some people in Science are pretty fucking kinky!), This document shows a number of interesting graphs, one of these is rectal pressure against Frequency, and Time:

As you can see there is a marked difference in pressure against time during Orgasm than during the other tasks. The Paper gives no indication of what the testing methodology was, however I believe that one way to sense this would be the use of a pressure sensor coupled with an inflatable butt plug (pressure off the air would change with rectal pressure).

In theory the butt plug would be inserted into the young lady; inflated till it was under pressure; the valve would then be closed; the analogue value read from the Pressure Sensor as a zero point.

With a little bit of signal processing you could abuse the feedback to turn off other machines before or during orgasm; and also hopefully before…

Now to purchase a few sensors and try it out.
