Aptly named "G-Point" to make the statement.
In blood red colour as well.
Note the well position centre button... I presume the vendor named that button the "G-Spot"

Turns out there’s an LED sensor under the small trackpad, just like the kind you’d see under an optical mouse. Only this sensor reads up instead of down and you move your finger instead of moving a device. Light from the LED reflects back from your moving digit and hits a sensor where the movement is converted into X- and Y-axis changes. (And here you thought you’d never use that simple third-grade geometry again!)
