Take a quick skip through the "romance" section of any bookstore and in between the themes of "I think I'm broken now" and "Where the hell is the love I want?" there are a slew of books about the amorous side of dating. Sex is a natural, if sometimes tricky, part of relationships, and the publishing industry is here to help us all out.

Two new books get creative in their approach to couples in bed.

Both make the obvious, yet often-overlooked, connection between the physical health of one's body and the physical health of one's sex life. Not only does a fitter body feel better and have more stamina, it makes the person inside it feel better about naked time. Most couples would cheer for that.

Better Sex Through Yoga by Jacquie Noelle Greaux ($17.95, Broadway Books): Before you start making jokes about downward facing dog, pick up a copy and peruse the 268 pages of this highly instructional book; at times, it begins to feel like an owner's manual for the body.

Greaux takes an athletic approach to improving sex through strengthened core muscles; improved sense of sexiness; creative, yoga-based positions and, well, diagrams.

She renames certain poses to be flirty (I don't remember the "cha cha cha" or "wild child" in my last yoga class, at least) while showing how to incorporate traditional poses into sex in a final short chapter called "Mind-blowing sex positions." We'll let you imagine how "the camel" fits in that equation.

Sure, this book is about sex and how to be a better lover for a partner, but it's solidly yoga-centric and proper in its explanation of positions' benefits to the body. So when you're single or not swinging, this book doubles as a guide for your inner yogi or yogini.

The Orgasmic Diet by Marrena Lindberg ($23.95, Crown): Apparently, somewhere around 40 percent of women have sexual dysfunction which, in essence, makes sex more chore than fun and may have them avoiding it altogether.

Lindberg claims that this is based on faulty brain chemistry and body function and sets out in the most scientific (and sometimes boring) way to help women fix the problems.

But boring may be OK if it works. She focuses on four areas: proper hormone balance, balanced brain chemicals, muscle tone below the belt and good circulation to that area.

She aims to bust the myth that "it's all in your head" by incorporating recent research into libido killers. Some of her suggestions include: a high-protein, low-carb diet; dark chocolate; fish oil; a reduction in caffeine, antidepressants, hormonal birth control and nicotine; and exercise of pelvic muscles.

Does it work? We here at Girl Talk have not done the official test, sorry. But Lindberg seems grounded in her advice and claims that two weeks is all it takes. So check it out and holla back.
