There are many flaws with your idea, Sex Wizard, but the biggest one is that it violates federal medical privacy rights legislation that went into effect this past weekend. Voluntary or not, being part of a program in which other people can check on any part of your medical history by just phoning in or typing in an access code is very dangerous. The idea may be for men looking for sex to have some protection but how are you going to screen out employers, insurers or a whole host of other folks who may want information for reasons that weren't originally intended?
