Soft Packers are designed to look and feel like a flaccid penis and testicles. They are often worn as prosthetics by trans and gender non-binary people, and they are sometimes used gender play or gender exploration.

Which Soft Packer is Right for Me?
When searching for the right soft packer, there are a lot of variables to consider. What size should I get? Do I want to find one to match my skin tone? How much money do I want to spend? Can I pack it comfortably? How realistic does it look/feel?

Inexpensive packers are often made out very soft, porous materials like elastomers, TPR, or polymer/oil blends. These materials will often have trade names like "soft skin," "cyberskin," "sil-a-gel," etc. Because they are so soft, they can feel quite realistic as a flaccid penis. They will tend to show wear, dirt, and even slight shrinkage over months of use, and they can never be completely sanitized. Porous packers usually have to be replaced periodically. But, they tend to be cheaper than silicone packers and are very squishy in feel.

Packers made from 100% silicone tend to be a bit denser and heavier than porous-material packers, but they can still be pretty soft.  In general, the softer the silicone, the more it is prone to wear and tear, so most manufacturers try to strike a balance between softness and longevity.  Silicone is a relatively non-porous material, and as such it can be sanitized and it doesn't get as dirty as porous-material packers. Silicone resists shrinking and fading, and in general will last a very long time (if you don't accidentally tear it). For people with sensitive skin, silicone can be a good choice as it is hypoallergenic.

When considering size, remember that flaccid penises tend to be much smaller than erect penises! The average flaccid length of a penis is between 3 to 4 inches long. Bigger doesn't mean better.

How to Care for Your Soft Packer
Wash your soft packer with warm water and a gentle soap. Rinse and pat dry with a lint-free cloth.

The surface of your soft packer may feel sticky due to the nature of the material. Unless the manufacturer specifically recommends against it, lightly dusting the packer’s entire surface with corn starch (available in the grocery store baking aisle) will keep the packer from sticking to your skin and hair, and will help it stay cleaner. The easiest way to apply corn starch is with a soft-bristle paintbrush or make-up brush. Do not use powders containing talc, or other body powders that may contain fragrance or other potential irritants to your genital area!

Soft packers are typically not designed for sexual penetration, unless they are a special "pack and play" type of packer.

Minimize wear & tear by wearing packer in a pocket-style harness or pocket-style packing underwear/jock. Many people sew simple pockets into their underwear as a cost-effective way to safely and securely pack.

A Stand To Pee Device (STP) is an item used by a person born with a vulva to urinate while standing up.  STPs can be convenient for when sitting or squatting to pee isn't an easy or attractive option (such as while camping or doing other outdoor activities, or in places where bathroom facilities are dirty or non-existant).  STPs that are shaped like penises are sometimes used by trans and gender non-binary people in order to feel more in tune with their bodies and/or to use gendered restrooms or urinals without incident.

What to look for when choosing a STP device
Much of the advice below is geared toward transmasculine people, who often have specific needs when it comes to privacy and safety when using an STP. But some advice will still be relevant to all users.

1. Will I be using the STP in privacy, or in a more public place like a urinal, campsite, or worksite?
If you typically plan to use your STP in a bathroom stall, or at home, or any other mostly private place, you might not care so much about how your STP looks, but rather how well it functions. However, if you are planning on using your STP in a men's room at a urinal, or in a semi-public setting such as a campsite, a boat, or a worksite, you may be concerned about what others will see if they catch a glimpse of your STP. If that is the case, you might want to consider a STP packer, or at the very least something that appears to be flesh-toned and that is easily tucked into your pants after use.

2. Do I want a STP that looks like a penis?
As noted above, certain situations for transmasculine people (like urinal use or other semi-public use of your STP) might be safer and less stressful with a STP that looks like a penis. But even for those who always pee in privacy, having a STP that looks like a penis may help them feel more at home in their bodies. Many transmasc people choose prosthetic penises with a STP option for this added sense of well-being.

3. How will I clean and store the STP when not in use?
Some STPs are designed to be easily folded and hidden in a pocket or a bag, while others can be a bit more unwieldy. Keep in mind how you plan to get the STP to the bathroom with you, and whether you'd like to rinse it out and store it again immediately after use.

TAKE NOTE: MOST STPs TAKE PRACTICE TO MASTER!
All STPs, especially STP packers, will take some practice to master. It is best to first practice at home, without your clothes on in the shower to get used to correct placement and flow. While still at home, practice in front of the toilet without clothes, and then finally try it at in front of the toilet while clothed. This is crucial if you plan on using a public urinal! It is better to have any accidents or mishaps at home than when you are out in public.
