Choosing and Using a STP

What is an STP Device? 

An STP device, short for ‘stand to pee device’, is—as its name suggestions—a  device that allows users to urinate while standing up. Some STP devices also  function as packers—objects used to create the appearance of a bulge where  somebody doesn’t have a penis—while others are designed to be used as stand alone devices.  

Who Uses STP Devices and Why? 

As with soft packers, one of the primary users of STP devices is transmasculine  people—transgender people who were assigned female at birth. For some people,  urinating while standing up can feel affirming of their gender, or ease dysphoria  they have around their genitals. Some transmasculine people may also find using  an STP makes them feel safer in male bathrooms, as it allows them to use urinals  rather than conspicuously waiting for a stall. 

People of all genders may also use STPs to make going to the bathroom easier or  quicker, especially in situations where stalls may be unavailable. While some  transmasculine people may want to use urinals because it makes them feel safer,  others may choose to use an STP at a urinal for convenience and speed. In  situations where flushing toilets aren’t available—such as when camping or hiking —people of all genders may find it useful to have an STP to use. 

Additionally, just as some people use packers because wearing one makes them  feel sexy, some people use STP devices in ways completely unconnected to gender  and primarily connected to sex. People with vulvas who enjoy watersports can find  they prefer the level of control an STP offers them. The structure of some STPs also  means they can be used for oral sex, as suction on the end of an STP can transmit  sensation to the wearer’s vulva if held against the body tightly. 

What Kinds of STPs Are There? 

As well as varying levels of realism, STP styles can be distinguished in a couple  of other ways. 

‘Medicine spoon’ style STPs take their name from the fact that before  commercial products were available, people would DIY their STPs with a soft  packer and an actual medicine spoon! The receptacle that cups the user’s body is  very small, so only tends to sit around the urethra. This can make them more  difficult to position than other STPs for some people. However, for a variety of  reasons—including urethra placement, body size/shape, and labia size/shape— some people find medicine spoon STPs easier to use. Some people also prefer this  style of STP, as the smaller receptacle makes shaking off excess urine easier.  

More common than ‘medicine spoon’ style STPs are funnel style STPs, like the  New York Toy Collective Sam. These—as the name suggests—are funnel shaped,  with larger receptacles that cup the labia. While the size and shape of the cup varies  between STPs, it’s generally easier to place than medicine spoon STPs, as it doesn’t  require placement to be as specific. Having a closed funnel and a large cup makes  some funnel STPs usable during partnered oral sex in a way that other STPs aren’t.  

How Do I Use an STP? 

While they may seem simple in principle, learning to use an STP can take some  time. It’s recommended that you try using your new STP at home before taking it  out into the wild. Even if you’ve used a different STP before, each model is  different, so it’s worth practicing at home. 

We recommend first practicing using an STP in the shower. This allows for easy  cleanup, avoids risking damaging clothes, and means you don’t have to aim at a  narrow target. To use it, place the STP’s cup over your vulva, making sure to create  a seal around your body that includes your urethra. Start with a small stream— some STPs have narrow channels in their shafts (which can make a full steam  difficult to control or not possible), you may not have placed the STP’s cup correctly  (which can lead to spills), or you may not be aiming correctly. Once you’re happy  with your placement and direction, and have a good idea of how how quickly the  STP’s channel drains, you may want to increase your flow’s heaviness.  

After you’ve mastered using your STP in the shower, you may want to try using  a toilet at home without any clothing on, before moving on to using it at home with  clothing, and then taking it out and about.

Once you’re become accustomed to using an STP, some extra tips include peeing  at a consistent rate, to create as smooth a stream as possible. A slight tilt backwards  in the pelvis can make your stream go further, while tilting forwards helps to avoid  splash back when using a urinal close up. 

How Do I Clean My STP? 

After each time you use your STP, you should at least shake it and dry the tip  with toilet paper to ensure no drops of urine are left. When possible, you should  wash it with warm water and soap. If you use your STP daily, you should wash it at  least daily as well. If you’re using what’s sometimes called a 3-in-1 or 4-in-1  prosthetic—which has both STP and pack-and-play capabilities—make sure you  wash your STP prior to penetrative sex. 

STPs are usually made of silicone or hard plastic, which can be sanitised. You  can either place an STP in boiling water, or—if your dishwasher has a ‘sanitise’  setting—place it in the dishwasher with no soap. 

Using An STP For Sex 

It’s not just the 3-in-1 or 4-in-one prosthetics—which generally have an  insertable rod which makes them firmer—that can be used for sex. Because STPs  create a seal around the genitals, suction on the end of the STP’s ‘shaft’ or channel  can be felt on the user’s vulva. The intensity of this suction varies depending on  STP style and individual anatomy— not all combinations of STPs and particular  anatomies can bring a person to orgasm (and some people may not be able to  orgasm from this stimulation at all). However, some people enjoy using their STPs  in this way and find this stimulation erotic, gender-affirming, or both.
