There are right ways and wrong ways to express ourselves sexually. This week, we explore where we draw the lines and open our minds.

Fifty Shades of Real

With the release of the "Fifty Shades of Grey" trailer, the buzz about BDSM has come back up to the top of water cooler and social media conversations, the media, and even between couples. But how well-informed are most people about BDSM? Not very, according to some sexperts.

However, unlike most kinksters who just simply trash the best-selling trilogy, Madsen provides some straight and direct guidelines for the basics of BDSM play and relationships: consent, safewords and aftercare.

Fetish sexuality psychotherapist Dr. Galen Fous believes that societal myths and beliefs about BDSM have forced many people to suppress, hide, or deny the truth about the truth about their personalities. He also believes that such societal stigma prevents people from researching, practicing, preparing for, and understanding how to consciously and honorably engage their kink. In his recent article on The Good Men Project, "Fifty Shades 2.0 - Time to Upgrade Your Kink Sexuality Knowledge Base," Fous explains how couples and partners should negotiate BDSM play, even if it’s just a one-time thing. He also insists that partners be honest, transparent and safe; that they fully understand the light and dark sides of their sexuality and, like Madsen, stresses the importance of after care.

For those of you getting into BDSM for the first time, Cassie Fuller (AKA Madame Cassie), founder of Touch of Flavor, offers BDSM classes in Baltimore. She also offers some really super - and super-safe - things to start off with in Women’s Health magazine. She also has a lot of great suggestions for things you can use around the house before you head out to the fetish shop.

Finally, whether you would ordinarily consider yourself or your partner kinky, fantasies are a normal part of our sexual selves. Sometimes they scare us and sometimes the thought of bringing them up with a partner or spouse can be even scarier. In "Hitched," Violet Blue offers some great tips on how to initiate a conversation about fantasies with your spouse.

Everyday Sex

When she was 16 years old, blogger Meg Conley swore that she would never be one of those women who were too tired to have sex. But after she and her husband had their first child, she became one of those women, and it bothered her. After an eight-day loveless stretch, she decided to do something about it: make a pledge with her husband to have sex every day.

It turned out to be a very workable and beneficial solution. For a woman who had been so tired that she said her bones hurt, Conley claims that she is less tired - and happier than ever. Check out her five reasons why couples should have sex every day.

Then there’s Mischa Badasyan, a 26-year-old man in Berlin. He’s not married, but he’s on a quest to have sex with a different man every day. According to Vocativ, the Russian-born performance artist says he’s pursuing this quest in the name of art. Badasyan will be creating photo and video installations, filming a documentary about the experience and building a sculpture from his bed sheets, as well as other items that remind him of his encounters. He has ads running in four Internet sex dating sites looking for muses and hookups.

The History of Sex Dolls

Sex dolls aren’t a 20th century invention. Julie Beck, a senior associate editor at The Atlantic, says that there is some implication that Ovid’s Pygmalion may have had sex with a statue he had fallen in love with before it became real. The Greek rhetorician Athenaeus wrote of a man who had a physical love affair with a statue of Cupid. French and Spanish sailors made love dolls from fabric. It's also rumored that Adolf Hitler charged one of his SS commanders to design sex dolls for German soldiers during World War II to prevent them from slaking their lust with non-Aryan women.

According to Beck, it wasn’t until 1968 that sex dolls could be ordered and sent through the mail, causing their popularity to grow. Since the late 1990s, sex dolls became less of a novelty and more life-like. Beck also takes a deep look into the psychology of sex dolls and their owners. It’s an interesting but lengthy read that’s worth checking out.

The History of High Heels

So how did high heels become such a sexy fashion statement? A Howstuffworks.com video claims strangely (or not-so-strangely once you watch the video) enough, any assumption that the first high heels were made for women is full of shit - honest! In fact, Louis XIV - not Christian Louboutin - was the first man to make red-soled high heels fashionable. As or why high heels are popular with women today, the video gives early feminism, porn and recent discoveries in evolutionary biology as the key reasons.
