This is called the Japanese tucking method, and it involves lifting the twins into the inguinal canals. Using this method will hide them completely and is recommended for the flattest appearance. Remember to gently shift them upward and into each socket. Guide them slowly. Do not use hard pressure, and stop tucking if you experience pain. The very first time you try this, it can help to take a cool bath or shower before to make the process easier. The twins naturally ascend toward the inguinal canals when they're exposed to cold temperatures. When the process is complete, your scepter will be back and under your perineum and the twins will be in their canal, inside your lower abdomen. Hold everything in place by applying pressure with your thumbs as shown.
Note: If you're having trouble with this technique, it may help (despite all this talk about cold) to first take a warm bath, allowing the twins to drop away from your body. Use this time to explore the area, pushing inward in the empty space with your fingers. This will give you an idea of the interior topology, if you will, that you have there. Remember: not all trans bodies are the same, so if you have difficulty with this method, feel free to tuck in a way that works for you! Many of our our customers say they're able to get a great tuck, even without using the Japanese method.
