You shop local. You eat local. Why not sex local?

Thus goes the premise for this fictional app from Adhoc that lets users find other people around their location who want to have "sexual intercourse" with them. No, we're not talking about people who want to date you in your city, we're talking people who want to have sex with you where you are. Right now. Classmates, co-workers, strangers in a park. 

Welcome to the future.
