If you see something, say something: With the Kinsey Reporter app, you can document each time you partake in some hanky-panky or witness someone else getting frisky in public. The app, which is free and anonymous, collects surveys about sexual behavior and then aggregates, maps and shares the data with users. Created in part by Indiana University's Kinsey Institute—which is named after Alfred Kinsey, who conducted groundbreaking sexual surveys starting back in the late 1930s—the app doesn't require you to write out any details. Instead, you check boxes on simple surveys. Though current reports don't ask about HIV, future ones might. Nonetheless, the accumulated data will provide more insight into sexuality and relationships. And that's news we can always use.
