close up of the Back- holder
The mini plate is glued between the bum cheeks, bellow the tail bone.
The elastic is too short to get in the way of using the toilet.
The elastic stretches as you move.
You move freely while the prosthetic stays in place.
The back -extension (on the prosthetic) is wide enough to not irritate the anus or crotch. It is thin enough to be barely felt.

B) Knob

- When flaccid, the knob tucks into a concave indent on the back of the prosthetic.
- The knob is not felt when the prosthetic is in the flaccid state.
- With an erection, the knob is pushed out.
- Due to its shape, the knob rubs against the small penis (hormonally enlarged clitoris) allowing you direct physical feeling. When erect, your prosthetic penis shaft feels like an extension to your natural penis.
- The knob is made of a slightly firmer silicone.
C) Erection release - Exit valve
A few twists to open the valve for air flow, or to close it air tight.

D) Air pressure regulator - Skin valve
- This is the small brown valve seen on the back of the prosthetic in several of the photos.
- It works automatically.
- The flaccid prosthetic stays soft and "lubricated" inside, as there is always a cushion of air between the prosthetic parts.
- With an erection, the air under the skin is pumped out, leaving the skin taunt against the veins and shaft.
- During airplane travel (as air expands) air is free to flow out of the prosthetic.
- The valves construction stops water from entering when you bathe and swim.
