Spine-Tingling Stretch
Think of Child's Pose as exercise foreplay. "The playfulness and receptivity of this stretch causes another's heart to open," says Naime Jezzeny, a yoga instructor and owner of Luminaire-Yoga.com, a hip line of yoga accessories.
How to do it: Do Child's Pose by getting on your hands and knees, then lowering your hips down to rest on your feet. Keep your knees wide and your arms outstretched. Rest your torso on your thighs; your palms and forehead should rest on the floor. Get your guy to face the opposite direction and align his spine with yours. He should then spread his arms and lie back over your curved spine, which acts as a support for his passive back bend. Then switch positions — it's a perfect opportunity to test his flexibility!
Body benefits: Your spine, arms, shoulders and legs relax when you stretch the lower back, while pressure on your belly stimulates your internal organs. (The close proximity is sure to stimulate you in other ways too!)

Play Ball in the House
Working out with a medicine ball solo isn't as much fun as passing it around with your guy. To get fab abs (and boost desire), try partnered obliques with a weighted ball. "Exercising large muscle groups elevates testosterone levels in both men and women, and it raises your libido," says Debbie Mandel, author of "Turn on Your Inner Light: Fitness for Body, Mind and Soul."
How to do it: Stand or sit back-to-back as you pass a weighted ball around yourselves in a continuous motion. (Keep one hand on top of the ball and the other under it as you pass it.) Do 25 reps, switching directions about halfway through. Build up to a heavier ball (up to 14 pounds) and aim for three sets of 25 reps. The faster you go, the better the cardio workout.
Body benefits: You'll lose the rolls and work your biceps, making it a breeze to hold yourself up when you're on top (or in other compromising positions).
