SEE HER MINDBLOWING ORGASM!


Interesting story on a woman who reached orgasm in an MRI machine.

For science of course.

It let doctors see which part of the brain she used as she climaxed.

The answer: Pretty much all of it!!!


Read the whole story and watch the video after the break.


The Female Brain during orgasm.








Dirty Minds: Writer Reaches Orgasm in Noisy MRI Machine

Jan. 11, 2012
Kayt Sukel was an undergraduate research assistant in a neuroscience lab at Harvard University before she decided to jump right into science -- literally.
She crawled inside a functional MRI machine, where she was tethered with a mesh net harness to hold her head still, and sexually stimulated herself to climax in that awkward setting -- not just once, but twice, so researchers could map her brain activity.
It was a scene even she admits felt straight out of a porno film, but Sukel said she knew she was contributing to the scientific understanding ofwhat happens to the brain during orgasm. And it made great fodder for a book.
"I did it," she writes. "I now had a great story if anyone ever asked me to name the strangest place I'd had an orgasm. And I had helped science while doing it. Triumph for all parties concerned!"
Sukel, 37, writes about that and much more in her new book, "Dirty Minds: How Our Brains Influence Love, Sex, and Relationships," which examines how neurobiology shapes how we love and bond with others.

Other books have been written about "the nether regions and what is going on downstairs," but this well-researched book helps readers find out "what's going on upstairs."
"Sex is between your ears," Sukel said. "Our brain is really an important part of orgasm."
One of her most surprising discoveries was that men's and women's brains in love are not that different.
"There is a lot more variation within any given sex than between them," she said. "There are more differences between 100 women in their brains than between men and women."
"A lot of biologists say women are this way in love and sex, and men are that way," she said. "But a lot of gender biases don't appear in the way you would expect in the literature."
Sukel explores what in the brain makes a person fall in love and why "good girls like bad boys." Is there such a thing as love addiction? And what does science say about attracting the right person?
"Romantic love really is a biological drive," she said. "Something in our biology makes us want to make connections."
When Sukel had her son, she discovered firsthand the infatuating love of a child, which serves an evolutionary purpose.
"My baby was pretty sexy -- much more than I'd been prepared for," she writes. "Not in a sweaty, naked-hot-guy kind of way, but in an irresistible, compelling way that altered my body, my mind, and my life from top to bottom."
During orgasm, as well as during lactation, the brain releases the so-called "love hormone" oxytocin.
"The adoration is part and parcel of it," she said. "If I didn't love this pooping, screaming machine as much as I did, we would not be able to commit."
Sukel's behavior made sense to her.
"I had to take care of a helpless thing, and thank goodness the biology helped give me the mental and emotional toolkit to cope with that," she said.
In studies of maternal behavior in prairie voles, oxytocin makes the female more interested in her offspring. And she gets faster at catching prey. In males, the hormone vasopressin seems to have a similar effect, encouraging monogamy.
"I know the jokes about men being like rats," she said. Nonetheless, it's hard to make rules about men and women. "It's clear men do form strong attachments."

Hormones Affect Development

Hormonal action on the brain starts early, even in utero. At six to 12 weeks gestation, a fetus with XY (male) chromosomes will get a rush of testosterone that helps create the developing penis.
"After that, there is another flood [of hormones] that basically gives the blueprint for all circuits," said Sukel.
"For so long we have talked about gender and love as being either biology or environment," she said. "But environment has a way of shaping biology and vice versa … an intricate dance."
Nowhere are brain circuits more alight than during the human orgasm, and Sukel wanted to learn more about the neurobiology of sex. Last year, she offered to support research at Rutgers University in New Jersey, plunging in to a noisy, cold MRI machine.
At first she felt competitive, wondering if any of the other subjects had failed at climaxing inside the loud machine. She was reassured by lead researcher Barry Komisaruk. "A few. But not too many," he told her.
Understanding the physiology of climaxing is still a mystery, according to Komisaruk, a professor of psychology at Rutgers and author of the 2006 book, "The Science of Orgasm."
Stimulation of the genitals triggers a cluster of nerve activity that moves to the sensory cortex in the brain, and then on to various parts of the limbic system. Most immediately activated are the amygdala, which controls emotion and heart rate; the hippocampus, which controls memory and fantasy; and the cerebellum, which controls deep muscle tension.

Next, the frontal cortex, which controls executive function, is activated, and then the hypothalamus, releasing oxytocin, and some other areas before "everything cools down," he said.
Powerful endorphins are also activated that raise a person's pain threshold. In both men and women, orgasm works roughly the same way, said Komisaruk.
His studies focus on which parts of the brain are activated in which sequence from the start of genital stimulation to orgasm.
"It's important because in many cases, people can't experience orgasm," he said. "The next step would be to find out where the blockage occurs. We want to follow this up with a possible therapeutic procedure to bypass or get around the block."
Therapy might involve neurofeedback in "real time," allowing a person to view the parts of the brain critical to orgasm and to direct the body to respond.
Komisaruk sees real potential with those who cannot experience orgasm because of paralysis or prostate surgery.
One woman, who was paralyzed from the waist down and had no external sensation in her genitals, was able to feel the orgasm in her uterus. Brain imaging has revealed that the nerves from the genitals run along the vagus nerve, outside of the spinal column, up to the brain.
"She didn't feel it in her clitoris, but could feel it in her vagina and cervix and she had muscle cramps," he said.
In another brain imaging study, some women have shown they can have an orgasm just by thinking about it -- without any stimulation.
"We obviously have the ability to think our brains into action, but we don't know yet what the limits are," said Komisaruk.
Sukel is intrigued by the way Komisaruk emphasizes "the bigger picture" in his research.
"What we are finding is the top-down control that can modulate our feelings of pleasure and pain -- it isn't limited to our organs," she said. "Think of the placebo effect … We have a lot of influence over our perception of pleasure and even over our disease state and will learn more going forward."
Orgasm just may provide a "novel way" to understand touch and allow humans to modulate their feelings, according to Sukel.
"It might go beyond biofeedback -- just believing that something is helpful," she said. "Even telling a patient their pain is not harmful reduces the sensation of pain."

Sorry I've Been Away

     It's been a long week of helping to take care of my friend with the brain tumor, on top of all the work I've been doing. A friend of mine gave me a book called "the 33 Strategies of War" by Robert Greene. It's part of Robert Greene's trilogy of book of strategies & rules; this one about war, one about power, & the last one concerning seduction (political & social, not sexual).

     These books are of the self help variety but are not your typical Tony Robbins psycho mumbo jumbo about inner peace & stuff. These books are more a kick in the ass & more reality based. So far, it's a great book & one where I find myself reading every paragraph 2 or 3 times in order to digest it all. That would explain why it's taking me forever to read it.
     My favorite passage so far (I'm only on strategy 5) is this one: "It can be valuable to analyze what went wrong in the past, but it is far more important to develop the capacity to think in the moment. In that way you will make far fewer mistakes to analyze.
     Think of the mind as a river: the faster it flows, the better it keeps up with the present & responds to change. The faster it flows, also the more it refreshes itself & the greater its energy. Obsessional thoughts, past experiences (whether traumas or successes), & preconcieved notions are like boulders or mud in this river, settling & hardening there & damming it up. The river stops moving; stagnation sets in. You must wage constant war on this tendancy in the mind.
     The first step is simply to be aware of the process & of the need to fight it. The second is to adopt a few tactics that might help you to restore the mind's flow."
     There's something to digest to a little while. Of course, I would've put it another way: JUST DO IT.

Carpe Diem

Most people sleepwalk through life. Like rats in a maze, they follow along a path trying to find cheese that never exists. I bring this up because a couple of weeks ago, a friend of mine almost died, through no fault of her own. One minute she was fine. The next minute, she had massive headaches & started throwing up. She was taken to the hospital, where the doctors sent her to emergency surgery. It turns out, she had a tumor lodged in her brain that moved into the wrong spot.


Now, she didn’t know she had a tumor. After all, it’s not something that usually shows up in your regular physical. The bad news is that it’s in a part of the brain where they can’t completely get at it to take it out. The good news is that it’s noncancerous.

The doctors moved it back so that it won’t bother her & the prognosis looks good for a full recovery. However, think about it. One minute, you have your life in front of you. The next minute, you’re being rushed to possible life ending surgery. Think about what you would give at that moment to do things better in your life. Think about the dreams you would give anything to have a chance to fulfill. How would you live your life, if given a chance to live again?

Now, she’s been given the chance to find out. I hope she takes what’s happened to her as a sign to finally live her dreams. There are no do-overs in life but most people live their lives like there are. Most people are like rats in a maze. Don’t be. Never give up on your dreams. If you don’t like your situation, change it. If you think it’s too tough, it’s because you’re limiting yourself. Changing your situation takes guts.

Most people are slaves to their past. There’s nothing you can do to change your past so get over it. There’s only the present & the future. Only one of those is guaranteed & that’s the present. The future never is. Life is precious & every day is a gift. Use the gift wisely. Use every day wisely. Carpe diem. Seize the day.

College Town Mall: Another Man's Girl Part 1

     I admit it. I enjoy have sex with other guys' girls. I don't initiate it but when it's offered, I indulge. There's some sort of perverse pleasure of knowing that a woman wants you to fuck her because her man isn't taking care of business.
     The first time I knowingly had sex with another man's girl was with a woman named Dotty. She used to come into the store a lot. She was a short redhead with a really tight body. Sometimes she was with her man; sometimes, she wasn't. One time, we struck up a conversation about a movie that had opened up. I asked her if she wanted to go. Surprisingly, she said yes.
     We went to the movie, then came back to my place. We sat on the couch & started watching tv. Dotty put her head on my shoulder. That's when I knew it was time to make my move. I lifted her head up & stared into her eyes. My index finger traced a pattern on her lips. I moved in & gave her a long kiss. She didn't flinch at all. After a few minutes, I stood up, reached down, picked her up, & carried her to my bed.
     I laid her down on the bed & started removing her clothes. When I got to her panties, she whispered "we can't. I have a boyfriend". Now, in my brain I'm thinking "well, if your boyfriend were that important, you wouldn't have gone out tonight & you certainly wouldn't have let me get you undressed this much".
     I could've done the right thing, let her get up, & walk away. Instead, I continued taking off her panties, split her legs apart, & started licking & sucking her clit. Funny how she didn't worry about having a boyfriend at that point. I kept up my attack on her pussy, licking her pussy lips & sticking 2 fingers into her. I wanted to prep her pussy for my cock. She moaned & thrashed while I worked her like a technician. Her juices flowed as she screamed & bucked her way to an orgasm.
     I stood up & took off my clothes. Standing by the edge of the bed, I grabbed her legs, pulled her towards me, split her legs, & grabbed her ass. Lifting her hips, I positioned the head of my throbbing cock next to her pussy lips. Pulling her hips towards me, I guided my cock into her & started moving her hips back & forth on it. The blood rushed to her brain as her body was arched backwards.
     She was mine to play with. I didn't care if her boyfriend ever found out. At that moment, all I knew was that this girl was mine & if I did her right, her pussy would always be mine. Even if I never fucked her again, her pussy would be wet at the very thought of me. She'd always compare her lovers to me, no matter what. My ego took over with those thoughts. My mission was clear: to give her the most erotic fuck of her life.
     I fucked her in that position for a while. Then, I stopped momentarily & pulled out of her. I flipped her over onto her stomach, split her legs again, pulled her towards me, lifted her up, & pushed my cock back into her. Her blood was still rushing to her head, since I had her sloped downward yet again.
     After feeling her pussy muscles tighten as she came, I went into overdrive. I put her stomach first flat onto the bed, then arched her ass up. Putting one knee onto the bed, I split her legs yet again & guided my cock into her. Arching one of her legs to the side, I grabbed her hair & yanked her head backwards. Using that as my brace, I pumped her hard, with everything I had. Her screams became deafening. Her will was gone. Her body was putty in my hands. My cock imposed its will upon her pussy, making her cum time & time again.
     We fucked for a few hours. Then, she had to get home to her man. The next day, I went into work to see a note in my work box. It was from Dotty, saying that the evening was fun but that we could never do what we did again. I figured I'd never see her again. I figured wrong....
