When it comes to the topic of sex, I've been known to put it all out there. As a matter of fact, on the very first episode of The Dr. Oz Show, I jumped right in—to the point of telling the audience personal stories about my sex life with my wife, Lisa.

Being in a healthy, fulfilling sexual relationship can do wonders for your overall wellness: Developing science suggests that the benefits range from keeping your heart healthy to helping you look younger. Here's why you should get frisky tonight.
