In Nature magazine, scientists theorize that dopamine surges may cause indiscriminate sexual desire. Could heavy porn use/masturbation (another dopamine-surge behavior) be behind some human homosexual and bi-sexual behavior?

Marital Spats, Taken to Heart
by Tara Parker-Pope of the NY Times
Recent studies show that how often couples fight or what they fight about usually doesn’t matter. Instead, it’s the nuanced interactions between men and women, and how they react to and resolve conflict, that appear to make a meaningful difference in the health of the marriage and the health of the couple.
As this article reveals, the search for sexual thrills is often about an addictive quest for high dopamine and an altered state, rather than sexual orientation. This is in contrast to sex that strengthens neurochemical equilibrium.
...the transgression and fear of being caught add an extra thrill to the experience ... and no one cares about your "orientation" in a lavatory -- in there, it's all business.
Neuroimaging reveals a shared basis for chocoholia and drug addiction
This article explains clearly how "natural reinforcers" like food (and sex) can become addictive.
Mounting evidence shows that compulsive eating and drug abuse engage some of the same brain circuits in similar ways, offering a new angle for understanding and treating obesity. In an interview with Scientific American, Nora D. Volkow, director of the National Institute on Drug Abuse and a pioneer in the study of addiction, explains.
When you're attracted to someone, is your gray matter talking sense -- or just hooked? Scientists take a rational look.
[Scientists are beginning to understand the problem of built-in biological decay in intimate relationships. Perhaps they will soon be willing to investigate the ancient solution for getting around it - making love differently.]
First comes love, then comes marriage -- but these two things are no longer inextricably linked to nor necessarily followed by "the baby carriage."
A new poll by the Pew Research Center finds Americans are de-linking children as the sine qua non of successful marriages. In fact, they now tell pollsters they rate "having children" as the ninth most important out of 10 markers of successful marriages.
FORGET the proverbial seven-year itch.
Not to disillusion the half million or so June brides and bridegrooms who were just married, but new research suggests that the spark may fizzle within only three years.
Researchers analyzed responses from two sets of married or cohabitating couples: one group was together for one to three years, the other for four to six years.
So revealed 109 women and 64 men who recounted nearly 3,600 dreams in diaries, reported psychologist Antonio Zadra, Ph.D., of the department of the Universite de Montreal.
About 45% of men said they'd had dreams about sex as did 41% of women, he said at the Associated Professional Sleep Societies meeting here. "There really is no gender difference between men and women offer who dreams about sex," Dr. Zadra said.
Contending that this was the first study in four decades to evaluate sex and dreams, Dr. Zadra and colleagues said that the diaries had been conducted for studies that did not involve sex.
People who are socially dominant and either very friendly or very antagonistic tend to be more sexually promiscuous, according to a new study.
Friendly, warm people may enjoy sharing their warmth with others by sleeping with them, whereas antagonistic people may sleep around to avoid having a monogamous relationship. And having a dominant personality makes it easier to approach potential partners.
Past studies have suggested that people who are dominant tend to have more sexual partners than people who are submissive, but there has been little research into whether a person’s level of interpersonal warmth -- the way in which they interact with others -- affects their sexual actions.
We have often wished we could explain to the makers of the imminent sexual enhancement drugs why such drugs are likely to create bigger problems than they solve. Increasing desire in the short-term doesn't automatically increase satisfaction. Here's an article from Discovery News about research that explains why desire doesn't equate with pleasure - and how this leaves us vulnerable to addiction.
