Sex can feel pretty great. But have you ever stops in the middle of it to wonder why,
What actually happens to your brain in body during sex?
There are a lot of different types of sex but for all the first step is usually arousal increased blood flow causes tissues like your chest to swell and your face to get what’s known as sex flush for those with a penis blood flowing gorges the three spongy areas along the length of the shaft creating an erection for those with vagina the opening inner and outer labia swell as well this increased pressure causes fluid production from both the Barthel and gland and skinny’s gland which helped to create lubrication in a woman neuro-transmitters are released to help relax the muscle in the wall and make the vagina both longer and wider there’s a white held belief that women require more time to achieve arousal.
But using thermographic cameras on people’s genitals while they watched porn researchers found that it took healthy men and women both 30 seconds to begin arousal and reaching maximum arousal around 10 minutes.
Researchers have actually documented penetrative vaginal intercourse by getting eight couples to perform missionary sex in an MRI tube, this study revealed that during intercourse two-thirds of the erect penis is pendulous and moved upwards at an angle of about 120 degrees from the root of the penis.
Meanwhile the uterus raises up by two point four centimeters and changes the configuration of the woman’s bladder a woman’s breasts may increase in size by up to 25 percent and men’s testicles can grow by 50%.
While rising closer to the body though all of the men orgasms in this experiment and none of the women did which isn’t uncommon a survey of over 1,400 women found that only 21 to 30 percent of women experienced an orgasm during intercourse that was not assisted by extra digital or oral stimulation.
Oral sex on women can provide direct stimulation to the clitoris the clitoris is actually much bigger than it appears and is about four inches long with about three-quarters of the structure being internal the clitoris and penis are similar they both have glands a foreskin also known as the hood erectile tissue and a shaft but unlike the penis the only known function is “Pleasure”.
There’s also anal sex which is the insertion of a penis or a dildo into a partner’s rectum though it’s the primary Orma sex among gay men its popularity has surged among straight couples.
A 2008 survey found that 44% of straight men and 36% of straight women have had anal sex your anus and surrounding area have a lot of nerve endings including thepudendal nerve which controls muscles in your external anal sphincter and carries sensations to the anus penis and clitoris and then penetration can stimulate the glandular organ known as the prostate.
Though there’s no published laboratory research anecdotal evidence suggests that prostate orgasms are more powerful and pleasurable than penile induced ones for women anal penetration can stimulate the perennial sponge which sits between the vaginal opening and rectum so pressure can result in pleasure and orgasm characterized by contractions of the genitals in the end.
You have the orgasm when it comes to the brain the experience is pretty similar for men and women and men dopamine synthesizing neurons are activated during ejaculation and in women the reward center that releases dopamine is activated too for both areas in the cerebellum become activated.
While significant parts of your cortex completely shut down at the same time oxytocin the hormone responsible for bonding is released from the pituitary gland making you more likely to cuddle up after sex so yes like all good things.
