Quick answer

To use a stand to pee device, position the funnel opening directly over your urethra, angle the tip downward, and keep a slight forward tilt so gravity moves urine out instead of pooling. Practice first in the shower with water before trying it at a urinal. A realistic flaccid STP like STP 1 or STP 3 gives you a natural profile, but the seal and angle matter more than the look.

Get the seal right before you worry about aim

The most common reason urine leaks is not the device — it is a gap between your body and the funnel. Hold the back of the STP against your body so the opening sits centered over your urethra, then press gently inward and slightly upward. You are creating a light seal, not a clamp. If you feel air escaping or hear a hiss, reposition before you start. A mirror helps for the first few tries, and so does sitting on the edge of a bathtub or toilet with your knees apart.

Angle the shaft down and forward

Once the funnel is sealed, tilt the shaft so the tip points down and slightly away from your body. If you point it straight down, urine can back up along the walls of the funnel. If you point it too far forward, you may overshoot the bowl. The sweet spot is usually a 30–45 degree downward angle. Keep your wrist relaxed; gripping hard distorts the funnel and breaks the seal.

Control the flow and breathe

Start with a slow, steady stream rather than pushing hard. A forceful start can overwhelm the funnel and cause splash-back or overflow, especially with a smaller STP like STP 3. Take a breath, relax your pelvic floor, and let the urine flow. If you feel resistance, stop, check the seal, and restart. Many first-time users find that counting to three before they begin helps them avoid rushing.

Clothing and cleanup that make a difference

Wear underwear with a snug but not tight waistband so the STP stays in place without pressing the funnel flat. A packing pouch, like the bamboo 3-pack pouch, can hold a soft packer or STP securely during the day and make it easier to reposition when you need to use it. After use, rinse the funnel with warm water and mild soap, shake off excess, and let it air dry completely before storing. Silicone can trap moisture in the reservoir, so drying matters as much as washing.

Step-by-step STP routine

  1. Practice in the shower with water: Hold the STP against your body, seal the funnel, and pour a cup of water through it while you adjust the angle. This lets you see leaks without the pressure of a public restroom. If water runs down your hand, the seal is broken — reset before you try urine.
  2. Position the funnel over your urethra: Center the opening, press gently inward and slightly up, and keep your knees apart. Use a mirror the first few times to confirm the placement. A hissing sound means air is escaping; shift the funnel until it stops.
  3. Tilt the shaft down and forward: Aim for a 30–45 degree downward angle so gravity carries urine out and away. Avoid pointing straight down or too far forward. If you feel back-pressure, the angle is wrong — adjust before you continue.
  4. Start with a slow, steady stream: Relax your pelvic floor and let the flow begin gradually. Pushing hard can overflow the reservoir, especially with a shorter STP like STP 3. Stop and reset if you feel resistance; do not force it.
  5. Rinse and dry after every use: Wash the funnel with warm water and mild soap, shake off excess, and air dry completely before storing. Moisture left in the reservoir can cause odor or irritation. Store in a breathable pouch, not a sealed plastic bag.

Product facts that help with STP use

  • STP 1 / STAND TO PEE 4.5 po: STP 1 is a flaccid, realistic penile prosthesis designed for standing to urinate, made from medical-grade silicone with a reservoir and leak-proof edges to help prevent overflow. The reservoir and sealed edges are what keep urine from spilling when you tilt the shaft; check that the edges sit flat against your body before you start.
  • STP 3 / STAND TO PEE 2.5 po: STP 3 is a flaccid, realistic penile prosthesis designed for standing to urinate, made from medical-grade silicone with a reservoir and leak-proof edges to help prevent overflow. Its shorter 2.5-inch profile can be easier to position for beginners, but the smaller funnel means a slower, more controlled stream works best.
  • (Soft Packer + STP) 3-PACK Packing pouch: The bamboo 3-pack packing pouch is designed for FTM, FTX, and non-binary people to wear a soft packer or STP daily, with an internal pocket and a 3.80 cm (1.5 in) O-opening to insert the prosthesis. A pouch keeps the STP from shifting in your underwear, which helps you maintain the seal when you step up to a urinal.
