A nice idea for the ladies out there is to insert a pair of ben wah balls and then go for a nice long walk.You could also try to see how far you can go before you lose one or both(with or without panties on).Having done this with a young lady before i know just how difficult it can be to keep the ben wah balls quiet and if the lady is wearing tight jeans/slacks she will find it almost impossible to hide the results from anyone
