This could either be a downer feature, or a good one. Either way, Apple's newest iPhone OS update - iOS 9 wants to help you track just how often you get jiggy with it in the sack. Healthkit, one of its pre-installed apps will not only track your fitness, nutrition and sleep, it will also track your reproductive health.

The app will track your basal body temeprature, which is your body's lowest resting temperature. It will also track cervical mucus quality, menstruation, ovulation test results, spotting, and finally, sexual activity.

Apple assures that this data is kept private by default and it is designed to work with pre-existing apps and devices that track reproductive health.

It would definitely be interesting to see just how many times you do it in a month, for sure.
