1. First, choose a posture that you think is most comfortable: you can lie down, or sit with your legs apart, or stand on a chair with one foot. Tear along the incision of the packaging bag and take out the sheath. The built-in elastic inner ring should be at one end of the sheath opening.
2. Squeeze the lower half of the inner ring with your thumb, forefinger and middle finger, so that you can tightly grasp and shrink the inner ring and put it into the body smoothly.
3. At this point, use the other hand to fold the labia majora at YD mouth separately, and push the squeezed inner ring into YD as far as possible.
4. Then put your finger into the sheath until you touch the inner ring, and then continue to push the inner ring into YD. When the inner ring has just passed through the pubic bone, the sheath is in place. You can put your finger into YD and feel the position of pubic bone, which is just a few inches inside YD.
5. It is normal that a small part of the outer ring and sheath will be exposed outside YD, so don't worry.
