Tucking is a technique used to create a smoother silhouette by positioning external genitalia in a way that minimizes visibility.
There are many options for tucking, and it is ultimately up to you what feels like the most supportive method.
At Floruisse, we developed tucking garments (also known as a 'gaff'), that have a pocket feature to help keep everything in place without slippage. This eliminates the use of tape, so that you may able to take the garment on and off as needed. Here is how to use the pocket feature:
Put your legs through the leg holes of the garment and stand up, pulling the waistband right below your hips. Gently tuck your penis back between your legs while inserting your penis into the pocket feature. Pull/tug the gaff upwards (not too rough!), from the center front and the center back of your body. Smooth out the waistline and leg holes.
For an even flatter look, you have the option to tuck in your testicles into your inguinal canals. The inguinal canal is located in your lower abdomen. The opening should feel like ring with a slight indentation. Place each testicle in the corresponding side. This should not be painful, but it might be uncomfortable. If you feel pain, stop and try again later.
Always use caution when sitting down while wearing a tucking panty. If you experience discomfort or an erection, loosen or temporarily remove the panty.
Pressure causes diamonds — however in this case, constant pressure to the penis and testicles may cause pain and/or infertility. To receive proper medical advice, please consult with your doctor before using the tucking function.
If this is your first time using a tucking undergarment, it might feel uncomfortable, but it should not feel painful. This is a comprehensive tucking guide, providing different techniques, options, and what to expect:
