| Body During Orgasm |
Although the reasons for having sex can be very varied and complex, reaching orgasm in general is the main goal. One thing that many people can agree on is that orgasm is a very intense pleasant experience.
So, what is orgasm?
If in doubt, open the dictionary. The Oxford English Dictionary defines orgasm as "a sudden body movement; like seizures, contractions, or vibrations due to spikes in sexual arousal. "Merriam-Webster describes this sexual experience in more detail, stating that orgasm is a series of physical signs and symptoms that occur at the peak of sexual pleasure which is usually characterized by ejaculation of semen in men and vaginal contraction in women.
Leading sex researcher, Dr. Alfred Kinsley once said that orgasm can be compared to the crescendo climax in a musical composition. According to him, orgasm is a gradual sexual pleasure, from calm that becomes increasingly loud, and ends with silence.
Three stages of the body's reaction to orgasm
Quoted from WebMD, William Masters and Virginia Johnson (two leading sex therapists) coined the term "sexual cycle response" to describe the sequence of events the body traverses when its owner is sexually stimulated and participates in sexually stimulating activities (penetrative sex, masturbation, foreplay, etc).The sexual cycle response is divided into four stages: sexual arousal, stable period, orgasm, and resolution. There is no clear boundary where a stage starts and ends - all of this becomes part of an ongoing process of sexual response. Keep in mind that this cycle is a very general outline of what happens to each body when we become sexually aroused. There are many variations between individuals, and between different sexual events.
Both men and women go through these four phases, the only difference is time. Men usually reach orgasm first during intercourse, while women can take up to 15 minutes to reach the same point.
1. What happens to the body when getting sexual desire
This phase usually starts within 10-30 seconds after erotic stimulation, and can take several minutes to several hours.Man: Penis becomes slightly upright. The testes swell, the scrotum tightens, and the penis begins to eject pre-ejaculatory fluid. A man's nipples can also harden and straighten.
Woman: Vaginal lubrication starts. The vagina swells and prolongs. The outer lips, inner lips, clitoris, and sometimes the breasts begin to swell. Breasts become fuller.
Both: Muscles tighten, pupils dilate, and your pain threshold rises. Heart rate, blood pressure and breathing increase.
There is an increase in vasocongestion, or tissue swelling caused by additional blood flow, which causes three common signs of arousal: nipples tighten, reddish skin, and erections.
At the same time, your brain is flooded with powerful hormones: dopamine and oxytocin, specifically. Dopamine, which is released first, triggers motivation - in this context, the motivation to reach orgasm. Oxytocin, which comes later, makes you feel bound (which is why it's called "hugging hormones").
As a pair of hormones, these two neurotransmitters can explain why we feel instantly - even if only briefly - are bound to our partners when we begin to feel passionate. Reporting from the Refinery 29, brain geography lights up like fireworks during sexual arousal: Half a dozen parts of the brain become active, including the amygdala (which is emotionally related), the hippocampus (which is associated with memory management), and the anterior insula (helps process physical feelings).
The male and female brains do not always respond in the same way to arousal generating stimuli. Men show deeper amygdala brain activity while women are almost non-existent.
2. What happens to the body when it is stable (plateau)
If sexual stimulation continues to occur, the next stage in the sexual response cycle will occur. This phase, called the stage (plateau), may or may not be disclosed, either verbally or through action or behavior.Male: The testicle is pulled into the scrotum. The penis becomes fully erect.
Woman: Vaginal lips become more bulging. The vaginal wall tissues, one third of the outside, swell due to blood, and the vaginal opening narrows. The woman's clitoris becomes very sensitive (it may even hurt to touch) and "hide" under the clitoral lid to avoid direct stimulation of the penis. The inner labia (lips) change color (although it is rather difficult to see). For women who have never had children, lips change from pink to bright red. In women who have had children, colors change from bright red to deep purple.
Second: The rate of breathing and pulse are accelerated. A "sex flush" may appear on the stomach, chest, shoulders, neck, or face (like blushing). Thigh muscles, hips, hands and buttocks tighten, and seizures may begin.
During the plateau phase, arousal stimulation can reach its highest level, can disappear, and then reappear several times. Once you reach the top of the plateau stage, orgasm will follow. During orgasm, all sexual tension is released. Just before orgasm, heart rate, breathing, blood pressure and muscle tension reach their highest peak.
Orgasm is the climax stage of the four sets of sexual cycle responses. This stage is also the shortest stage of sexual response, usually only lasts for a few seconds.
3. What happens to the body during orgasm
In men, physiological changes when reaching orgasm include semen that accumulates in the urethral sphere. This condition occurs when a man feels sure to have an orgasm, or what is called the "necessity of ejaculation". Next, the penis releases ejaculation. Contractions also occur in the penis during the orgasmic phase.For women, the orgasmic phase will be characterized by a contraction of one third of the front vaginal wall with an eight-second beat of the beat. (The amount and intensity of contractions vary depending on the orgasm experienced by the individual.) The uterine muscles also contract, although they are barely felt.
In general, the orgasmic phase will be felt when the rate of breathing, pulse and blood pressure continue to increase. Muscle tension and swelling of blood vessels will reach its peak. Sometimes, orgasm comes with a "grasping" reflex on the muscles of the hands and feet.
For men and women, there are four types of nerves that are responsible for sending information to the brain during orgasm. Hypogastric nerves send signals from the uterus and cervix in women, and from the prostate in men; the pelvic nerve transmits signals from the vagina and cervix in women, and from the anus in both sexes; the pudendal nerve transmits from the clitoris in women, and from the scrotum and penis in men; and the vagus nerve transmits from the cervix, uterus, and vagina in women.
Differences in male orgasm and female orgasm
Although both sexes tend to engage in different behaviors when engaging in sexual activity, the male and female brains are not too different. During orgasm, lateral orbitofrontal cortex - the area of the brain behind the left eye - is deactivated during orgasm. This region is considered to provide logical reasons and behavioral control. The brains of both men and women during orgasm are said to look like the brains of people affected by heroin, according to the Medical Daily, according to a study from the Journal of Neuroscience.
Women involve more emotions and a sense of security, men regard sex as a relaxing activity
The difference between the two sexes lies in the periaqueductal gray (PAG) - a part of the brain that is activated when a woman is involved in sexual relations. PAG is part of the brain that controls the fight-or-flight response, and it is not activated in men when they reach orgasm. The study also found that women experience decreased activity in amgydala and hippocampus when they reach orgasm, which helps control fear and anxiety.
What does this difference mean? Researchers theorize that these active parts of the brain are because women need to feel safe and relaxed to reach orgasm, something that might not be important for male orgasm. Researchers also believe that men may be less affected by oxytocin (chemical bonds), which is released during orgasm.
Oxytocin can inspire feelings of closeness, affection, and intimacy, and some people theorize that this is the reason why women may be more susceptible to feeling after sex. The researchers showed that testosterone levels in the male brain might fight oxytocin and make men less affected by intimate feelings, making casual dating and sex have a superficial meaning for them.
Women can reach orgasm many times, men need time to recover
After the orgasm phase goes down, the individual will be welcomed by the phase of resolution or recovery, which is characterized by the return of normal bodily functions. The hardened and swollen body parts also slowly return to their normal size and color. This phase is characterized by a sense of happiness and general comfort, increased intimacy and, often, fatigue.
In addition, the main difference between the female and male orgasmic phase is that far more women than men have the physical ability to reach orgasm many times in a short time without having to "fall" into the plateau phase first.
However, the phenomenon of multiorgasm will depend on stimulation of stimulation that continues and also sexual interest of each party. A woman may not always experience any of these determinants, therefore repeated orgasms do not occur in any sexual relationship.
On the other hand, after ejaculation, men will enter a recovery phase called the refractory period. During the refractory stage, further orgasm or ejaculation is physiologically impossible. The duration of the refractory period varies from one man to another, and usually will be longer following age. However, some people can learn to reach orgasm without ejaculation, making it possible to reach orgasm repeatedly.
