Spanx -- it's the wonder piece of apparel touted by Oprah (hey, what Oprah says goes!), worn by millions of women for everything from first dates and weddings to job interviews. The concept is simple: Slip it on and watch that little pudge vanish into thin air. At least, that's what we feel like. But what actually happens to, you know, the extra? Is it really gone, or just pushed somewhere else?

Don't get us wrong: Spanx can feel sexy at first. And If you've seen Bridget Jones, you know what we're talking about. It starts early in the night, when you pull on a pair of Spanx over your tummy. All that tucking in makes you feel like you've lost five pounds (without dieting or a single push-up!), and suddenly you're oozing sex appeal. Your guy picks up on this and can barely make it through dinner without ripping off your clothes. And just as his hand slides up your leg, it hits you -- you're still in the Spanx. Could anything be less sexy than a piece of clothing designed to pull in fat?

Some designers are taking notice and are attempting to make shapewear sexier with new designs. Clever? Perhaps. But is it possible to make oversized pantyhose hot? We're asking you: To Spanx or not to Spanx?

We know you've done it: "Oh, baby, you did all the laundry and cleaned up the kitchen. Now come here!" Um, and by here, we mean bed. It's enough to make feminists everywhere cringe, but the reality is, women have been trading sex for chores since man met mop. And if you don't believe it, just ask the Council of Contemporary Families (CCF), who reported that men are doing more chores than ever -- and having better sex for it.

Here's how it works: Men grab the vacuum, or the sponge, or that nasty toilet scrub brush, and all of a sudden, women feel that their marriages are more equal. They're happier. They're satisfied. They're...ready to get it on. So weight in: Are you turned on when your husband goes all Mr. Clean? Do you ever use sex as a "trade" for his handiwork?

Sex can be like driving a car. Some people like to go fast. Others barely hit the speed limit. But if you and your spouse enjoy riding differently, well, let’s just say there could be bumps in the road. Okay, enough of this analogy. Take our quiz to find out if the two of you are compatible in bed (or wherever else you like to get it on).

According to the General Social Survey, which includes data on the opinions of US citizens and dates back to 1972, married Americans are having sex about 58 times a year -- barely more than once a week. And The Kinsey Institute, basically the epicenter of sex research, found that the "one or twice a week" average hasn't changed since they started collecting info in the 1940s and '50s. The good news is that couples under 30 are doing it 111 times a year, on average. So why the big discrepancy? The growing number of sexless marriages (read: couples who have sex 10 times a year or less) is messing with the average. And those marriages, studies have shown, are more likely to be unhappy and potentially end in divorce.

So why do couples start having less sex or stop having sex at all? Bob Berkowitz and his wife, Susan Yaeger-Berkowitz, surveyed more than 4,000 men and women to find out for their book, He's Just Not up for It Anymore. Their findings: The top two reasons men stop having sex with their wives are that she isn't adventurous enough and/or doesn't seem to really enjoy it. We did our own "study" to find out whether having more sex makes a difference in relationships. Check it out, and comment below on what you do to get out of a sex rut (or avoid one altogether!).

It's here -- the birth control you've been waiting for. No more pills. No more messy condoms. No more shots or rings or spermicides. So what is it? Well, the withdrawal method. Otherwise lovingly known as "pulling out." No, that's not a typo. Researchers at the Guttmacher Institute have released a study saying that not only is the withdrawal method effective at preventing pregnancy (most of the time -- and only if used correctly), but that women in their late 20s and early 30s are ditching condoms and opting for, ahem, the luck of the withdrawal.

What do you think about this? I mean, sure, once you're married, STDs aren't as big of a concern, and pregnancy, even if unplanned, doesn't pose the same panic-inducing what-am-I-going-to-do feeling that it might have before your wedding. But it still could be a gamble. Would you trust "pulling out" for your birth control method?
