Indiana University last year approved -- and then quickly unapproved  -- the release of a sex reporting app by its Kinsey Institute, long famous for cutting-edge sex research. Using the app, individuals could report promptly (and anonymously) on their own sexual activities, potentially giving researchers new information on exactly what people do and when and how they do it. The university denied it was being prudish and said it needed only to review privacy protocols. Following months of review, the university announced  Wednesday that the app has again been approved for release -- with only one change. That change is that all reports will be placed on hold for geographically defined areas. Only when enough people from a given area respond so that reports could not be linked to any one individual will that information move into the database where it can be studied.
