According to this article, yes the brain is the biggest sexual organ.
For almost a decade, researchers at Pfizer Inc. struggled to show that Viagra, the company's male impotence drug, could enhance sexual function in women. Last month, they gave up.
Countless tests on thousands of women made it clear that the little blue pill, though able to stir arousal, did not always evoke sexual desire.
Viagra's failure underscored the obvious: When it comes to sexuality, men and women to some extent are differently tuned. For men, arousal and desire are often intertwined, while for women, the two are frequently distinct.
Scientists recently have begun to map out how this difference shows up in the brain.
For example, male arousal, studies find, is strongly visual, and when men engage in sexual activity or even anticipate it, brain structures once thought to have little connection to sex spring into action.
The same brain regions, however, remain relatively quiet when women are aroused.
At the core of the sexual divide, some researchers say, is the amygdala, an almond-shaped nugget embedded in the limbic system, the brain's seat of emotions. Once thought to be involved exclusively with emotions like fear and anger, the amygdala is now believed to be more complicated.
In one recent study, a team of researchers at Emory University had 28 men and women look at erotic photographs while an MRI took snapshots of their brains. A pattern immediately emerged. The photographs set off a frenzy of brain activity, particularly in the amygdalae of men. Yet the two groups reported equal arousal most of the time.
"This definitely emphasizes that up until recently the amygdala has been overlooked," said Dr. Stephan Hamann, a professor of psychology and the lead author of the study, which was published online by Nature Neuroscience last week and is scheduled to appear in the journal in April. "Often, the amygdala is involved in the anticipation of positive emotions, which this parallels nicely with."
Hamann pointed out that the amygdala is known to have intricate connections to primates' visual systems.
One reason for the powerful response to visual stimuli in men, he said, could be cultural. Men tend to be inundated with sexual imagery and, possibly, are more likely to seek it out.
Evolution also may have a role. Some experts argue that, over time, men naturally became more dependent than women on sight in selecting a mate.
"For millions of years, men have had to size up a woman's reproductive capacity by looking for signs of youth and health that would enable them to carry a healthy baby," said Dr. Helen Fisher, an anthropologist at the Center for Human Evolutionary Studies at Rutgers, and the author of a recently published book, "Why We Love: The Nature and Chemistry of Romantic Love."

Skin is the biggest organ period. Skin is a driving sexual organ (in my opinion) so skin is the biggest sexual organ

The skin it has the most nerve receptors and is also the largest organ of the body.

Your brain. Without it, nothing's going to happen.

I'd have to say the skin-lots of nerve endings sensitive to being touched and licked.

I'd agree with the brain.

The largest organ you body has - your skin! Just think of all the places that can be scratched, rubbed, massaged... :)
