I'm sure that now you are laughing or at least giggling to yourself, thinking that I am a nut. But, ladies and gentlemen, I am serious. Food should only go IN your mouth. This includes all food not just the phallic shaped ones.
Feel free to put these things ON your body but not IN your body.
Unless of course you enjoy the hell that is a yeast infection or don't mind being sedated while a doctor removes food that has been lost in your internal cavity.
