Sexual intercourse affects the brain

It's not the easiest subject to study—test subjects might have to masturbate in an MRI machine—so research is still developing. But scientists are starting to unravel the mystery. Here's what we know so far about your brain on sex. That's why we want it, like it, and spend so much time hunting for mates. The pleasure we get from sex is largely due to the release of dopamine, a neurotransmitter that activates the reward center of the brain.

Sex: How does it impact brain activity?

Read now As for the amygdala, it is known to be involved in the regulation of emotions , and dysregulations of its activity have been tied to the development of anxiety disorders. An older study from the same university — which focused on brain regions that were activated at the time of ejaculation — found that there was an increase in blood flow to the cerebellum, which also plays a key role in the processing of emotions. The researchers liken the activation of the cerebellum during ejaculation to the pleasure rush caused by other activities that stimulate the brain's reward system. The regions that were "significantly activated" during orgasm, the team found, included part of the prefrontal cortex, the orbitofrontal cortex, the insula, the cingulate gyrus, and the cerebellum. These brain regions are variously involved in the processing of emotions and sensations of pain, as well as in the regulation of some metabolic processes and decision-making.

How does sex affect your brain?

How do sex hormones affect brain function? Sex also increases levels of oxytocin, the bonding and trust hormone, and decreases levels of the stress hormone cortisol. Not only does this feel good immediately, but tests of longevity in men show that greater frequency of orgasm is associated with increased lifespan. And women who have regular sex have been shown to have significantly higher levels of estrogen in their blood compared to women with infrequent or no sex. Estrogen helps maintain a healthy cardiovascular system, reduces bad cholesterol, and increases good cholesterol, increases bone density and enhances skin.

This is a significant number because it represents how many times humans have sexual intercourse on a daily basis. It is a number that alludes to something a vast majority of us already know — people love having sex. When it comes to humans, sex is incredibly fascinating, because save for dolphins and Bonobos an ape relative we are pretty much the only species that has sex for pleasure rather than just strictly purpose. But, what is it about sex that feels so good?

    I used to have a scene where you were doing this young red head on a couch.It started out with you licking her shaved pussy kinda gently. Then you added a finger, then two fingers and began finger banging her hard. She was obviously new to porn. After some serious fingering and generally making her pussy sore. The cameraman always wanted to see her young twat spread open.After she gave you an amateur BJ you layed on the couch with her in front fora while. Then you switched to doggy and really fucked her good. Even destroyed her ass too. If you remember this scene please upload it. I will be most appreciative. Thanks.
