Have you ever wondered why the foreskin and frenulum are so sensitive compared to the rest of the penis? As it turns out, you can thank your Meissner’s corpuscles: nerve endings that are especially sensitive to light touch and vibration. Meissner’s corpuscles are also present in your palms and fingertips. Try running your fingers along the back of your hand and then along your palm, if you want to feel the difference.
Thanks for the good sex, Meissner’s corpuscles!
