Orgasm is one of those experiences that almost all human beings. some people have serious difficulties in achieving it or never do. Although it can be worked on and solved – we feel at some point in our life (or several) and that does not differ by sex, gender, race or economic level.
And yet, it is possible that it is one of the bodily responses that we least understand or that we do not fully understand. Some people liken it to sneezing and the release that comes from doing so. However, the bodily responses and everything that happens in our body during orgasm , is not like anything else.
What is orgasm
Basically, orgasm is the the culmination of sexual arousal – not necessarily the end of sexual intercourse – which leads us to release the tension accumulated during the phases of arousal and is accompanied by a sensation of intense pleasure.
In the case of men, orgasm is accompanied by ejaculation, expelling the sperm. While in the case of women fluid from the Bartholin’s glands and fluid from the Skene’s glands can be emitted . Some research has found that women suffer uterine contractions that could have a reproductive function helping to retain the sperm inside, facilitating fertilization.
Arousal has several phases: it begins with desire, we move on to excitement and the plateau. In each of which the level of arousal increases, causing our breathing rate, heart rate and blood pressure to also increase. . Finally, orgasm is reached, where that tension is released and the resolution phase is passed, returning our body to the state it was in before the arousal phase.
In the case of men, they would go through the refractory period in which, for a certain time, they cannot have another orgasm. These different phases of the sexual response cycle do not have a specific time , but for each person – and in each different sexual relationship – they can take a different time.
What we do know is that, indeed, the sexual response phases make up a cycle and, after orgasm and the resolution phase. You can return to the desire and excitement phase , continuing with the cycle.
What happens in your body when we have an orgasm
We already know that orgasm is one of the last phases of the sexual response cycle, in which the tension accumulated during the previous phases is released, giving rise to the return to normality of our body, in addition to fulfilling the reproductive function of the sexuality.
However, what exactly happens in our body during orgasm? Why do we need the resolution phase to return to normal levels and recover? How many parts of our body are involved?
Role of Sexual organs in Orgasm
Of course, the sexual organs are one of the parts of our body that are affected by the presence of orgasms. In the case of women, the vagina is slightly enlarged, lengthening and widening , and it becomes lubricated. In addition, uterine and vaginal contractions occur. For men, it increases the rate of prostate and penis contractions. Also, of course, ejaculation occurs.
In women, just before orgasm, the clitoris contracts up to 50% of its size and at the moment in which orgasm is reached, it enlarges again, increasing in size. In addition, the breasts also swell a little and the nipples harden , which also happens in men.
Our skin is not exempt from the effects of orgasms. In this case, it is due to the effect that blood pumping has on our dermis. When having an orgasm the blood pressure increases and this can be seen directly on our skin as it becomes red. In some skins it is, of course, more visible than in others, but if it happens to us it is totally normal.
Our pupils are great telltale of our physical states, if we know where to look and what to look for. In the case of orgasms, the pupils dilate. This is due to the activation of the sympathetic nervous system. This is in charge, among other things, of controlling our most basic reactions and reflexes.
The heart is involved in everything we do and is affected by our activities, so it is not surprising that the arrival of climax affects our heart rate. Our heart rate can go up to 90-100 beats per minute, and can even reach 130 beats per minute, although this happens. In women , up to 170 beats per minute may be achieved.
Blood pressure also rises although, surprisingly, it rises the most during the plateau phase according to some research.
One of the parts of the body that, surprisingly, is affected by the presence of orgasms is the feet. Indeed, when our body releases the tension accumulated during the arousal cycle, the sensation can spread throughout the body, generating muscle spasms in the feet that, in some cases, can cause cramps.
In addition to the sexual organs, the brain is the big star during orgasms. We must bear in mind that, during sexual intercourse, countless nerve endings are involved and all of them send signals to our brain.
This causes some areas of our brain to be activated and others, instead, to be deactivated . The amygdala, cerebellum, pituitary gland and nucleus accumbent are activated, releasing endorphins, oxytocin and dopamine, in addition to influencing our control of emotions and muscle functions, among other things.
Reward circuits are activated, reasoning and control capacity is reduced by inhibiting the lateral orbifrontal cortex , which is completely turned off during orgasm, and the cortex is stimulated, among others.
In short, although it only lasts a few seconds, the arrival of orgasm is an important – and pleasant – alteration of our body.
