What’s Your Sex Fitness?

You’re familiar with the Fitbit…a wristband that measures your daily activity, calories burned, and sleep.  Well a UK company is developing the SexFit…a vibrating ring worn around the base of the penis that measures calories burned during sexual activity.  More specifically, it measures thrusts during sex.  We’ve known sex is a great form of exercise where different muscles are used, men can burn about 4 calories per minute, and women can burn about 3 calories per minute…all while having fun doing it.  But SexFit may make sex exercise (“sexercise”) a competitive sport.  The information collected by the device is accessed from the free mobile app and can then be shared and compared with friends.

Check out Bondara’s website for more information.  The prototype is under development and expect to undergo product testing this year, so it will be some time before it’s available.

Women’s Life Plans Have Changed

The average American woman’s life plan has changed drastically over the last few decades.  It’s no longer start having sex, get married, and have a kid…all within 4 years.  It’s now start having sex…continue having sex for about 9 years…then get married and have a kid in the year after that.

This means young women will need effective birth control for many years until their plans change.

Are you surprised by these changes?

While parents may avoid having this talk, kids actually see their parents as go-to sources of information and support for these issues.  Don’t let gender, sex, and sexuality become off-limits topics in your home.

Research by Georgetown University found that knowledge gaps among very young adolescents (ages 10-14) may lead to poor sexual and reproductive health once they become adults.  The experts recommend investing in sexual and reproductive health programs and policies targeting these youngsters:

As younger adolescents experience rapid transitions to unfamiliar experiences and face life-changing situations such as leaving school, having sex, becoming parents or acquiring HIV, parents, teachers and concerned others have a narrow window of opportunity to facilitate their healthy transition into later adolescence and adulthood.
