Tucking may be used by people who identify as:

– trans women
– trans femme
– gender nonconforming
– nonbinary
– agender

Some people may also tuck for aesthetic purposes, for cosplay or drag. Tucking will allow all these individuals to achieve a smooth appearance and hide any external genitals.
How to Tuck:

Tucking may be mildly uncomfortable, but it shouldn’t be painful. Don’t force your genitals to move. If you’re having difficulties or experiencing a lot of discomfort, stop. Take a break, and return later.

Practice tucking a few times when relaxed and in a comfortable space at home before going out. This can help you to avoid any panic or stress in public if it’s your first time tucking.
Step 1: Choose your panties.

There are different types of panties that work well for tucking, so you may have to experiment a bit to find the kind you prefer. Pick panties that are made of tightly woven Spandex or some kind of microfiber blend. Stay away from cotton or silk; natural fibers are “slippery” and can cause things to move once you have them in place. Cotton also has a tendency to stretch over time.[/caption]
Step 2: Tuck.

There are mainly two ways to do this. So try whichever maybe more comfortable to you.

First way: Put your tucking panties on. There are different types of tucking panties, such as specially made things called “gaff”. Then you take your penis (preferably your non erect penis), and pull it back toward your butthole, pushing everything—balls and all—backward.

In this way the font part of your pelvis is flat and your balls are between your legs, bisected by your penis, which is headed south toward the border. The penis lifts and separates the two contenders so that you have one testicle on either side delicately nestled like eggs between your thighs. It’s important not to get a hard-on as you begin the process. From this point on put all thought of romance or sex out of your head. If you get aroused, all hell could break loose. Then you adjust the fierceness of the tuck by pulling your panties up between your butt-cheeks in the back. Once in place, the panties will keep the whole package securely wrapped and bonded. Generally, as long as the tuck isn’t too tight, it doesn’t really hurt.

Second Way: Take your penis and pull it back between your legs. Begin with tucking the testes. The testes will slip back up into the inguinal canals. You can use two or three fingers to guide them up to their corresponding canal. Don’t rush this step. If there’s any pain or discomfort, stop and try again after a short break.
Step 3: Adjust the tuck.

Pull the panties up between your cheeks in the back until the tuck feels secure. Once in place, the panties will keep everything from moving. There are differing opinions about how painful this process is. Some say there’s no real pain as long as the tuck isn’t too tight; others describe it as excruciating but say it gets less painful over time as the bodies adjust to the new arrangement.
Step 4: Use Tape

You can also secure everything with a tape. Tape the backward towards the buttocks using a piece of 1″ tape or two pieces–one on each side several times. This is to keep the penis in the center and pulled back. There are two recommended types of tape–medical tape and duct tape. Medical tape will be less painful to remove, but be careful. If it gets even slightly wet, it will not stick. Duct tape is said to be the favorite of drag queens everywhere. It has a fairly strong adhesive, so security should not be a concern. It can be tough to remove, though. Soak in a warm bath and remove carefully. Avoid using duct tape if you’re freshly shaven as it can cause irritation and/or a rash.

Is it safe?

There’s been little research published on the long-term effects of tucking. Some risks that may occur are urinary trauma, infections, and testicular complaints. You may experience some light symptoms of chafing from tucking. Always check for any open or irritated skin before and after tucking to prevent infection.

Make sure you’ve gone to the restroom before you tuck. Sometimes tucking can hurt the penis: With the balls stuffed inside hot canals all day and the dick pulled backward, blood flow can be constricted, which can damage tissue. Sometimes you’re tucked and your dick gets hard—it’s just the way it is. The tucked hard-on is a real phenomenon, and it’s very painful.
