If our grandmothers are to be believed, people are obsessed with sex. It's sex, sex, sex all the time with you people. However, an increasing number of studies are showing that just the opposite is true. From Japan to the entire European Union, birth rates and libidos are declining, and governments have begun stepping in to shore up the national mojo.Obviously, the problem isn't that everyone's listening to Jimmyjane staff grandmothers. There's a plethora of reasons for the trend, from libido-killing birth control pills to obsessive iPhoning. But the solution probably doesn't lie in paying couples to have sex (we're talking to you, Taiwan). Here are five ways to take action and eliminate your own personal Sex Drive Deficit. 1. Shake it up. The best way to stay interested in sex is to, well, keep it interesting. If you're feeling like you've fallen into a routine, try initiating sex differently than you typically do – at a different time of day or in a different room of the house. Breaking this initial part of the routine will open the whole experience up to new things – from new positions to a new pair of wrist restraints. 2. Do it more often. In many ways, the sex drive works on momentum. The more you do it, the more you'll think about it, and the more you may find you want it. If you're having a hard time kickstarting your libido, you may want to... 3. Take some "me" time. Ladies, solo masturbation with a vibrator is a great way to develop a healthy fantasy life and figure out what sensations feel best to you. If you're worried you'll develop some kind of addiction to your vibrator, fret not: Studies have shown that women who use vibrators experience better overall sexual function. 4. Flirt. Yes, even if you're in a committed relationship. And no, we don't advocate getting physical with the object of your eyelash-batting. Flirting is an excellent (and harmless) way to stir up and channel your sexual energy. 5. Get visual. While previous studies indicated that women do not become aroused by pornography as quickly as men, those studies also required female participants to wear uncomfortable insertable metal probes. So. New studies show women are very turned on by erotic imagery, such as these lady-friendly sites and films recommended by sex educator Violet Blue.
