Let's face it. Most of us have those days where we're tempted to use the old "I have a headache" excuse. But wouldn't it be a heck of a lot more fun just to take care of your sex drive like you take care of other aspects of your health? Try these tips:

• Exercise. Aerobic exercise gets your blood flowing, boosts your energy, and triggers endorphins. And when you incorporate exercise into your daily routine, you'll just feel better about yourself and confidence has everything to do with feeling sexy.
• Relax. A stressed-out mood isn't exactly made for the bedroom. In addition to your cardio workouts, try yoga or tai chi -- they offer mind-body benefits that can help you relax.
• Add a little novelty. And I don't mean novelty in the bedroom (although that's not a bad idea, either). Spend some quality time with your significant other doing something different -- go for a hike, play a game of tennis, or try your hand at a rock climbing wall. Any activities that have you working together will help increase your physical awareness of each other and will strengthen your relationship.
• Get your vitamins. Some supplements, such as Ginkgo biloba, have been linked with sex drive, but the science is sketchy at best. You're better off just sticking to a healthy diet including a wide variety of fruits and vegetables.
