Wiring Sexual Tastes to Hairless Genitals...Oops!

Are we waxing away the line between adults and children?

At present, our culture both underestimates the power of erotic cues and misinterprets their significance. That is, sexual cues are presumed harmless because sexual tastes are thought to be hardwired whatever one views. Two circular assumptions follow from this faulty premise: First, we assume that what one climaxes to reveals one's unalterable nature; and second, we assume that if one begins climaxing to something incongruous one is merely discovering one's "true" nature. Such flawed reasoning arose in part due to medical politics which gave rise to a staunch refusal to investigate the plastic effects of sexual behaviors on the brain's delicate reward circuitry.

¿Por qué la luna de miel termina?

'No Sex Please We're Married' article(traducción de Francisco Moreno T.)

¿Conoces tú alguna sólida relación que parecía tener mucho a su favor... y que sin embargo terminó? ¿Qué hay con un matrimonio que se mantiene unido, pero sus miembros parecen estancados... o incluso hostiles entre sí? ¿Has visto la revista Newsweek el artículo Sexo no, por favor, estamos casados? Si la falta de armonía nunca ha afectado tu relación tú eres raro; en el 2002 en los EE.UU., la Oficina del Censo predijo que la mitad de los nuevos matrimonios era probable que terminaran en divorcio.

Nuestras lunas de miel no son duraderas, pero cuando vemos las estadísticas de divorcios a menudo asumimos que esto debe ser un problema reciente. No lo es. Es proverbial que "el período de luna de miel dure menos de un año. Lo que ha cambiado es que ahora podemos divorciarnos fácilmente cuando se produce la falta de armonía, y así lo hacemos. Por lo que un viejo problema, que estaba oculto en el pasado por el hecho de que las parejas tenían que permanecer juntas incluso cuando las cosas fueran difíciles, ya está saliendo a la luz.

Audiobook coverThis is a three-part YOUTube series we helped create, based on the audiobook, Things You Didn't Know About Porn.

It's an unsettling fact that by age 11 most boys have been subjected to pornographic images. Yet few materials on the subject address such a youthful audience. If you're a parent, it can be surprisingly difficult to find a good way to discuss pornography. You don't want your child to see sex as "forbidden" or "dirty," but no matter how sex-positive you are, you sense that porn isn't the best way to gain a sex education.

Hugs for Heroes

heroMen who are willing to experiment with foregoing orgasm are my heroes.

To be sure, most of them only make the experiment because they have exhausted all the usual alternatives. But then, so did I. Perhaps they are tired of feeling restless and anxious because a partner “isn’t giving them enough sex.” Or maybe they have rationally tried to solve the excess-libido problem on their own by producing orgasms with the help of Internet porn, or some other outlet—only to discover that this course of action left them hungrier than ever, that is, increasingly dependent upon the compelling brain chemistry of their chosen stimulation reinforced by orgasm.

Practical Pair-bonding

coupleWhat about those few exceptions to the rule: couples who are in love twenty years after marriage? Curious scientists had a look at their brain activity recently:

The Neurological Basis of True Love

They say "romantic love" was invented by the troubadors of the Middle Ages. They also say it doesn't last. But Rutgers University anthropologist Helen Fisher and colleagues reported today that functional brain imaging studies show that being "in love" transcends both culture and time.

couple hit by a seagullAs we’ve seen in earlier articles, neurochemical urges motivate mammals to eat, drink and have sex. Specifically, dopamine surges in their primitive reward circuitry send them after the things that further their survival—or at least the survival of their genes.

But what about the handful of mammalian species who have evolved to team up in order to do a better job of raising their young? They may get all the food, water and sex they want, and still feel that something is missing—until they are mated.
