Why We Fantasize: The Science of Sex

If you want to enliven your next dinner party, bring out this question: what was the subject of your last sexual fantasy?

Forks and jaws might drop, but only because almost everyone in attendance will be recreating the scene last played in their head, or claiming that they don’t fantasize, or claiming to only fantasize about their partner. However, chances are everyone at the table (assuming you’re not dining at a senior center) has erotic and illicit fantasies, and does so on a normal basis. But rarely, if ever, do we want to talk about it.

Titillating Taboo
Sexually fantasies are something we rarely discuss, even among good friends. Our deepest sexual thoughts are often considered too weird, perverse, or just plain wrong to be shared amongst polite company; fantasizing might indicate there is something wrong with our relationships, or worse, ourselves. But research indicates that having sexual fantasies is an absolutely normal, if not necessary, part of being a sexual being. It’s not having them that is aberrant.

Large research studies indicate that almost everyone fantasizes and almost none of us talk about it. While researching his book, Who’s Been Sleeping in Your Head: The Secret World of Sexual Fantasies, Brett Kahr, a psychologist based in the UK, anonymously surveyed 18,000 people in Britain and America. He asked them questions about the frequency and content of their fantasies and found that nine out of ten people have sexual fantasies. What’s more, he believes the remaining tenth person has them too, but is too embarrassed to admit it.

Even those of us that admit to fantasizing are reluctant to discuss what it is that gets us going. Ninety-five percent of the research subjects had never detailed their fantasies to another person. While some fantasies might be better left undisclosed—such as revealing to a new partner that you think about an ex while having sex with him—we don’t even talk about our imaginative sexual escapades with friends. Erotic fantasy is taboo.

Wine Me, Dine Me, 69 Me
Many people suffer shame and guilt about the perverse nature of their fantasies, even though what we think of as “perverse” may actually be quite common. Though a typical and unremarkable fantasy for both men and women is dreaming about sex with their current partner, Kahr also found that bondage, incest, sadomasochism, and voyeurism are also part of the varied fantasy life of “normal” people.

Fantasizing is one of the most basic ways to stay sexual no matter what else is going on in your life. I write at a blog designed to inspire moms to have sex more often, despite the stresses of having small (or big) children. We encourage fantasizing as a way to stay in touch with your sexuality, your femininity, your very adult-ness when you're stuck in a world of small children!

Sexual fantasy is, as the author points out, a normal part of the human condition. Many of us may secretly harbour secret desires we wouldn't necessarily want to discuss over the dinner table. My view is that as long as nobody get's hurt or damaged by the process, pretty much anything two consenting and willing adults do with each other is fair game. My current girlfriend and I have a really remarkably broad sexual repertoire, but then we respect and trust each other 100% in matters of love-making. Nothing really is off the menu if we are both up for it. The result is that both our sets of fantasies are fulfilled, we feel closer as a result and we have a mind-blowing time together. The idea of resorting to a more sedentary love-life with someone else, should we ever split up, seems an unappealing prospect as a result!

Even though I'm a spry 45, I was a little offended by this sentence: "However, chances are everyone at the table (assuming you’re not dining at a senior center) has erotic and illicit fantasies, and does so on a normal basis." What makes you think that senior citizens don't have fantasies, that the sex drive stops after you turn a certain age? In doing research for my upcoming book, What Women Really Want in Bed, we found that women of ALL ages fantasize, and vividly, and the same holds true for men. Please reconsider your age-ist beliefs about sex. Otherwise, good article. Cynthia Gentry
It feels good to write.
