Track Your Sex Activity With Apple's HealthKit

An update to Apple's Health app that is set for release this fall will let users track their sex lives, but experts say this tracking feature alone has little value for people's health.
Rather, it's only when information on sexual activity is integrated with other measures — such as the date of a woman's last menstrual period — that such tracking becomes useful, experts said.
The sexual activity tracking feature will be included as part of a new "reproductive health" section within Apple's Health Kit app, which will be available with the iOS 9 update.
