Sometimes, your muscles have clamped down from stress—it’s called a vaginal spasm. It’s your body saying, “I’m scared! No touch!” The solution? More relaxation, not more force.
Take a break. Drink a glass of water. Watch two minutes of a funny animal video. Your muscles will eventually unclench. Then, try the squat again. You can also bear down gently, like you’re trying to have a bowel movement, to push the tampon closer to the opening.
This is the same muscle magic that helps push out a baby, just a much smaller load. No pressure (literally).
