In sexually active people is quite well developed part of the brain that contains the memory cells. People who regularly experience orgasm increase their intellectual development, but on the condition that a permanent sexual partner. You have sex in the blood of the body produces adrenaline and cortisone. It is these two hormones stimulate the brain.
But it is not so simple. Sex - it's not just physical intimacy, which we enjoy. The key word here is "fun." Not all people find this approach in bed to give each other a pleasant. And if you do not have an orgasm, it does not mean that the proximity of the person does not feel any pleasure.
