A British company called i.Con is accepting early-bird registrations for a sex wearable that’s being marketed as a “the world’s first smart condom.” It will retail for about $US74 when it launches later this year. It turns out the device is not a condom at all, but rather, a ring that fits over a boring, standard-issue condom and measures the quality of sex based on several metrics, including speed of thrusts, calories burned, and duration of session.
