Recent Design Updates

What am I working on right now?

The prostheses sit and move realistically, but I want them to flop more – I want no resistance to the flop of the flaccid penis. I have lots of new ideas for how to achieve this  – that is my current focus.

Main design changes to the Phase4 since May 2017

  • Improvements to vein details and colouring of skin at erection
  • Softened the plate edges (as soft as the rest of the skin)
  • Softened the back of the prosthesis (stiffness now at knob only)
  • The knob is set further into the penis shaft (knob has no contact to body when the penis is flaccid)
  • Inside parts shortened (softer flaccid penis)

Changes to the Phase4 design since November 2016 = since begin of Phase4


  • Penis shaft insides are smaller and softer (Now the inside parts stay in the penis when flaccid, you don’t need to move the parts into the scrotum)
  • plate edge is slightly narrower, thinner and flatter
  • Improved placement of the band holes – (Now it is easier to attach, and hair camouflages the plate better)
  • swim valve is more efficient  (easier pumping, and easier to open and close)
  • connection of pump to skin is re-designed (it’s easy to re-connect them now)



t2 Simple updates

  • They are now one size only and all include the connection for the STP.
  • Improvements to the band connections and plate.
  • I updated the lube valve system, and
  • re-designed a few aspects to improve the general look as well as durability. (See t2 Simple)


Overview of Phase4 versus Phase3

Major changes since Phase3

  • There is now a hole through the penis shaft for use with an STP device. (You receive an improved version of the JetP. The Phase4 can also be used with many other STP devices).
  • The stimulation knob and the base of the penis will now stay firmly in place regardless of erection angle
  • Achieving and keeping full length at erection is now simple and uncomplicated.
  • The flaccid state is now smaller and softer. (Erect sizing is the same as the Phase3).
  • In terms of durability, all problems reported during the Phase3 have been fixed (except, that which what I cannot fix:  soft silicone rubs down and develops holes over time.)

JetP Updates for the Phase4 and updated t2 Simple prostheses

  • The ‚catch’ edges of the new JetP are larger and the hole is slightly smaller. This increases to seal area, making the JetP easier to place.
  • As always, you cut the JetP length to fit your body.
  • I have added a connection piece to make it easy to attach or remove the JetP quickly whenever you want to.
