I always suspected that orgasms were good for the brain and now science has validated this. In a new book called the Science of Orgasm, researchers scanned women's brains as they were sexually stimulated. They found that during orgasm, many parts of the brain light up using oxygen, which is always good for the brain.Another interesting finding is that many women who have severe spinal chord injuries can still feel sexual stimulation - even when doctors predict that they would not be able to do so. The authors of the book posit that there is actual another nerve, which they call the vagus nerve. This is what allows people to have sensation, even when traditional sensation-transmitting parts of the spinal chord are damaged.So - our pussies are directly connected to our brains. Literally. That may be the case but it's also important to remember that our pussies are connected to our brains symbolically as well. We have to be turned on in our heads to be turned on anywhere else. In fact, I would say that the brain is the body's biggest sex organ. Start there, and you're heading down the right path.How much is physical stimulation and how much is mental? We may never know - but they go hand in hand.
