STP Freely

by TG Supply


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

We spent countless hours researching and testing STPs in order to design a device that was attractive, functional, and affordable. Sturdy enough to hold its shape when you're using it, but soft enough to pack comfortably all day long. The STP Freely is never sticky, even after washing, and will never need powdering.

A complete review of the STP Freely

I've been wearing this packer almost every day for about 6 months. This is my pros & cons list so far

Pros: -Very comforable, even after all day use -Makes a natrual looking buldge - After some practice, it is a VERY easy stp to use - I never have to hold back my flow while using it - The slicone used is soft and comforable. -Theres a good amount of detail to make you feel connected to your prostetic

Cons: - As someone who is mixed race, none of the options really fit me well at all. The carmel is far too pale, and anything darker would be too dark. If you have tan skin, don't expect it to match you. - I know for a $45 dollar prostetic, you can't ask too much. But I do wish they offered a more expensive painted option for those who want more details - You have to wear very tight athletic boxers if you want this guy to stay in place. Anything else, and you'll be sporting a semi all day long.

Overall, if you want one good afordable STP to use every day, this will be great for you. This packer has given me confidence to stp anywhere, and it gives me a great looking buldge. If you don't mind your guy downstairs being one color, and you don't mind wearing tighter boxers, GO FOR IT. You won't regret it.

Overall really good, would definitely recommend!

Great for packing! Easy to learn and use if you are new to STP's. would also recommend buying the cake bandit STP boxer briefs 3" inseam as an add on so the packer won't move around! But comfortable for packing with normal boxer briefs if you are just planning on chilling at home.

STP Freely

has some flaws

The cup portion is far too soft. It’s way too easy to press it against yourself too hard, causing overflow/back flow.

Great for at-home use!

I really like this STP Freely, and have been using it pretty consistently since purchasing. When I’ve tried to use it as a packer, I’ve had trouble with positioning and it looks too large and/or erect in a way I’m not comfortable with. I am able to position it so it is barely visible and wear it out, but I have yet to find a way to wear it as a natural looking packer so I can use it when in public. However, at home as an STP device it is absolutely perfect. It’s taken some practice, but the design is intuitive and works great.
