Learning About Safe Tucking Practices

What is genital tucking?

Genital tucking (also known simply as "tucking") reduces the appearance of male genitals by positioning them a certain way. The testicles can be tucked into the passage through the muscles of the abdominal wall (inguinal canal). The scrotum and penis may be secured between the legs towards the buttocks. Sometimes both are done. The genitals are held in position with underwear, tape, or compression underwear used for tucking. This type of underwear is called gaff.

Why is it done?

Tucking is done to affirm a person's gender identity. It can increase a person's comfort and safety and reduce misgendering (referring to a person using the wrong pronouns). Tucking can have a positive effect on mental health.

What are the risks?

Tucking can cause poor sperm quality. Talk to your doctor about fertility options if you plan to have children using your own sperm.

How can you practice tucking safely?

There are many ways to practice tucking. Here are some safe ways to do it.

  • Start slowly to let your body adjust. Try tucking for shorter amounts of time at first.
  • Stop if you feel any pain. Some discomfort is normal at first.
  • Take breaks from tucking to give your body a rest. Untuck if you notice any of these symptoms:
    • Discomfort
    • Skin irritation
    • Soreness or tightness
    • Pain in the testicles or penis or pain when urinating
    • Overheating
  • Don’t tuck while sleeping.
  • Stay hydrated. Use the bathroom when you need to.
  • Avoid underwear or gaffs that are too tight.
  • Use only medical-grade tape. Don't use duct tape, scotch tape, or packing tape.
  • Shave or trim the area before using tape.
