Collection: Stand-to-Pee Devices

What Is a Peeing Dildo / Stand-to-Pee Device?

A peeing dildo — also called a pee dildo, STP dildo, or stand-to-pee device — is a hollow silicone prosthetic shaped like a realistic penis that allows the wearer to urinate while standing. Unlike a simple urination funnel, a peeing dildo has a lifelike external appearance and integrates urination function within a realistic form factor — making it the preferred choice for trans men, non-binary individuals, and gender-nonconforming people for whom the realistic aesthetic is part of the affirming experience.

The distinction between a dildo pee device and a standard female urination device (FUD) is primarily aesthetic and functional depth: a FUD is optimised purely for outdoor or practical use; a pee dildo is designed to pass visual inspection and function as a packer simultaneously.

FTM STP — Stand-to-Pee for Trans Men & Non-Binary People

For FTM (female-to-male) trans men and non-binary individuals, an FTM STP device addresses a core aspect of gender dysphoria: the inability to use male restroom facilities standing up. Using a transgender STP device changes that — making public restrooms, camping trips, and any situation where standing urination is the norm more comfortable and affirming.

Key considerations when choosing an FTM STP:

• Channel diameter & flow rate — A wider internal channel reduces the risk of overflow during normal urination flow; too narrow causes backflow
• Cup seal design — The base cup must conform to the vulva to create a reliable seal; silicone flexibility is essential for this
• Realistic vs non-realistic — Realistic peeing dildos pass visual inspection in male restrooms; non-realistic funnels are lighter and more compact for travel
• Combined STP-packer function — Many designs function as both a packing prosthetic and STP device, eliminating the need for separate items

STP Packer — Packing & Urination Combined

An STP packer is a dual-function device: it serves as a packing prosthetic for everyday gender affirmation — creating a realistic bulge under clothing — and as an STP device for urination when needed. For many trans men, a combined STP packer is the most practical daily solution: one item for two functions, worn in underwear throughout the day.

What distinguishes a quality STP packer from a basic funnel:

• Soft, floppy silicone shaft — Designed to hang and move naturally in underwear, not rigid like an erect dildo
• Concealed internal channel — The urination tube is integrated internally, invisible from the outside
• Skin-matching tones — Multiple skin tone options for authenticity under any light condition
• Harness or brief compatibility — Some STP packers are compatible with packing underwear or harnesses for secure all-day wear

Practical Use: Outdoor, Travel & Daily Life

Beyond gender affirmation, stand-to-pee devices are used by anyone who needs to urinate standing up without access to private facilities:

• Camping & hiking — Avoid crouching in open terrain; maintain hygiene in the absence of restroom facilities
• Festivals & crowded events — Use portable urinals or outdoor spaces without disrobing
• Travel — Airport layovers, long journeys, and destinations with limited private facilities
• Medical or mobility needs — Post-surgical recovery or mobility limitations that make sitting difficult

How to Use a Peeing Dildo / STP Device

1. Position the cup base firmly against the vulva, centred over the urethral opening. The silicone should create a seal against the skin.

2. Angle the shaft downward and slightly away from the body. Practise the angle over a toilet before using in public.

3. Urinate at a moderate, controlled flow. Too fast a flow exceeds the channel’s capacity and causes overflow.

4. After use, shake the device to clear residual urine from the channel. Rinse with clean water at the earliest opportunity.

5. A small amount of water-based lubricant on the rim improves the seal and comfort during extended wear.

Tip: Practise at home over a toilet for several sessions before relying on the device in public. Most users find a reliable technique within 3–5 practice sessions.

Frequently Asked Questions

Q: What is a peeing dildo?

A peeing dildo (also called a pee dildo or STP dildo) is a realistic hollow silicone prosthetic that allows the wearer to urinate while standing. It combines the appearance of a realistic penis with a functional internal urination channel, and is widely used by trans men, non-binary individuals, and those seeking practical standing urination solutions.

Q: What is an FTM STP?

An FTM STP is a stand-to-pee device designed specifically for female-to-male trans men. It allows urination while standing — typically in male restrooms — and often combines packing (creating a realistic bulge under clothing) with STP function in a single device.

Q: What is a stand-to-pee device?

A stand-to-pee device is any tool that allows a person with a vulva to urinate while standing. Designs range from simple cup-shaped urination funnels to realistic peeing dildos with integrated STP channels.

Q: How do I use a stand-to-pee device correctly?

Position the cup base firmly against the vulva over the urethral opening. Angle the shaft downward. Urinate at a moderate flow rate — too fast causes overflow. Practise over a toilet at home before public use. A small amount of water-based lubricant on the rim improves the seal.

Q: What material are Domlust STP devices made from?

Domlust STP devices are made from platinum-cured silicone — body-safe, non-porous, hypoallergenic, and flexible. The flexibility allows the device to conform to different body shapes for a better seal. Silicone can be boiled for sterilisation and is durable for long-term use.

Q: Are stand-to-pee devices reusable?

Yes. Rinse with warm water immediately after use. Wash with mild antibacterial soap for full cleaning. Platinum silicone can be boiled for sterilisation. Allow to dry completely before storage.

Q: Can STP devices be used with packing prosthetics?

Some STP devices are designed as combination STP-packer units — functioning as a packing prosthetic during the day and as an STP device when needed. Check individual product listings for combined STP-packer functionality.

Q: How discreet are stand-to-pee devices?

STP devices are compact and can be carried in a pocket or small bag. When positioned correctly under clothing, they are not visible. All Domlust orders ship in plain, unmarked packaging.
