STP Freely

by TG Supply


Transguy Supply's signature stand-to-pee device.



We spent countless hours researching and testing STPs to design an attractive, functional, affordable device. Sturdy enough to hold its shape but soft enough to pack comfortably all day long. The STP Freely is never sticky, even after washing, and will never need powdering.  

Pair this STP with a Cake Bandit Harness that can be worn under any underwear or the Cake Bandit STP Boxer Briefs, designed specifically for using an STP.

100% Body-Safe Silicone


  • Shaft Length (measured from top): 4 inches
  • Shaft Length (measured from bottom): 3 inches.

  • Cup Outer Width: 2 inches.
  • Cup Inner Length: 3.5 inches.
  • Cup Outer Length: 4 inches

    Silicone may be cleaned using any one of the following methods:
    - Hot water and soap
    - Diluted bleach
    - Running through the dishwasher on the top rack

    This STP packs easily and can be packed up or down. 

    Pair with any Cake Bandit Harness for the best fit.

    For first-time users, we strongly recommend you practice in the shower before attempting to use it in public. Even if you have had success with other STPs in the past, every STP is different and requires some getting used to.

    Thank you!

    The stp and boxers we're a bit odd to get use to especially with how to where and use them properly since i haven't the slightest clue but, but the vids on the sight help and it made me feel more comfortable in my skin slowly but surely, I appreciate it a bunch and with how realistic it looks!

    Needs a strap

    Partner loves it! But we do wish it came as a starter pack to include the strap, too.

    Great STP

    This is my first STP and packer alike. It fits my anatomy perfectly and I have had a few accidents however that was a fault of my own. So far it works fine in my normal boxer briefs, I didn't need to buy the harness, however it's difficult to have the cup positioned correctly at all times automatically when I go to pee. It packs very well also, they don't stick up in boxer briefs and they don't move around too much unless I'm running quickly or jumping. I don't have a problem with the cup concaving or anything, it's very structurally sound and easy to use.

    Euphoria in a box, get it!!

    My very first STP was this one. Bigger than I expected, but I didn't mind. Nice to pack with, easy to use pee-ing wise, and easy to clean. That silicone is remarkably soft- and wearing this w a harness gave me amazing eurphoria. Plus, the package arrived VERY quick. I live in the USA ofc, but it only took a week!!
