We're coming up on the most romantic day of the year, and while it's typical for most couples to book an expensive night out at a fine restaurant or a nice hotel, I think you should spend this Valentine's day at home. More specifically, spend it in the bedroom, if you get my drift (and how could you not?) Why? Because sex is really, really good for you.

Not only does it burn calories and improve your physical stamina, it helps improve your mood and increase your energy -- so it will actually help you slim down, and a meal at a fancy restaurant definitely won't do that. Plus recent research shows that it lowers your risk of so many health problems out there -- heart disease and cancer, to name a couple. The best part, given our current economic situation? Like Dita Von Teese says, It's totally, 100% free.
