One of the pleasures of life is, well, pleasure. A light airy touch from a feather awakens the skin’s sensitive nerves. You can do it to yourself, starting with your arm or face. Or better yet, guide another person to “feather” you, like a massage, or a lover as foreplay. A turkey tail feather works best for me, better than the manufactured, dyed commercial “ticklers”. It has something to do with the lite stiffness at the end of the tail feathers and the more direct connection to a real feather.
