I've tried the butterfly thingie and it really didn't do the job. It's too difficult to keep it positioned right where you want it. But I came across Ruby LaRue's and they sound really neat!
Quote: Ruby LaRue patent pending 100% cotton, sanitary, wash-n-dry crotches were designed for the pleasure of undergarments. This revolutionary design stimulates the crotch area by gently massaging the wearer's crotch during general motion and thereby increasing libido. They are not electric nor vibrational and are drug and herbal free. As the wearer moves, Ruby LaRue is designed to move with her. Sitting, standing, walking, riding in a car, or even swaying side to side will provide the wearer a scintillating pleasure of a sexual nature. The days of plain cotton panties and jeans are over for even the most prudent of ladies. Once you have experienced the essence of Ruby LaRue designer crotches, you will desire to add them to your daily wardrobe. Give them to your friends and you have given them hours of pleasure to remember.
WE PLAN to continue designing Ruby LaRue products with one RESULT in mind...Putting smiles on women's faces even on their busy work days. We DESIRE to adjust their attitudes by giving them COMFORT and PLEASURE from their garments.
