its begin in the desire
This is a term that describes everything we are going through during sexual activities – the human sexual reaction.
The first ones to discuss this term were Masters & Johnson who addressed unintentional physiological reactions from the initial stimulation to orgasm and relaxation.
Later on, other researchers added emotional aspects to sexual experience. Helen Singer Kaplan added another component called “sexual desire during the passion stage” that relates to the emotional readiness to have sex.
: Awakening or excitement
A mental and emotional stimulation, arising through dealing with sexual contents either through fantasy or by visual or sensual stimulation in reality.
At this stage, the female lubricates due to the excretion of lubricants from the edges of the vagina while the male develops an erection.
The symptoms, such as chest and upper belly redness due to the expansion of skin blood vessels, begin 10 to 30 seconds from the beginning of the arousal.
The men’s penis is now semi-erect, the women’s nipples stick up, the lower lips and clitoris swell, the vestibule lips flatten, two-thirds of the vagina expands and lengthens inwards.
This is normally the longest stage, along with the relaxation stage. The length of this stage changes from one activity to another and for different persons.
: The plain or plateau
Increased sexual stimulation until orgasm.
This stage progresses according to the degree of stimulation and continuity, if insufficient or discontinued there will be a slow relaxation and If there was enough stimulation, the stage progresses to orgasm.
This stage is characterized by the redness of the thighs and buttocks’ skin, increased blood pressure, rapid pulse, frequent breathing, increased voluntary and involuntary muscle tension in the body.
For women, the size of the nipples and breast size increases, the lips grow twice or three times their normal size and their color changes to dark purple due to blood vessel congestion as the orgasm approaches.
The clitoris sticks up, grows and disappears under the foreskin, swelling, and shrinkage in the external third of the vagina and narrowing of its orifice.
For the men, the penis base muscles contract, the testicles approach the body, the urethra closes so that the sperm does not mix with the urine and pre-ejaculation fluids are ejected.
:The Orgasm
The orgasm occurs as soon as muscle tension and blood congestion reach their peak. During the orgasm, congestion in the blood vessels is released and the muscles relax, blood pressure and heart palpitations are at their peak.
This stage takes a few seconds. The intensity of this stage varies from one sexual activity to another and from person to person. With women, there are regular pelvic floor contractions every 0.8 seconds and their intensity decreases.
Some women also report contractions in the anus and uterus. Female orgasm usually has no ejaculation. Some women experience urethral fluid emissions.
Women usually have an orgasm from the clitoral stimulation, although some claim that they reach orgasm without it.
Researchers claim that this irritation is also an internal irritation to the clitoris and clitoral feet.
For men, contractions of the penis begin to decrease their intervals (drawing of the clitoris and clitoral legs.) and this is manifested by sperm ejaculation, penile and sometimes lower back contractions.
These contractions are expressed as feelings of pleasure and liberation.
Relaxation or resolution
During the relaxation stage there is a decrease in sexual tension, the body begins to relax, and return to the state that was before the stimulus.
At the relaxation stage, men do not respond to sexual stimulation.
In contrast, some women may have more orgasms while stimulating in the same sexual activity known as multiorgasm, while some women will not prefer post-sedation stimulation due to clitoral sensitivity and even experience pain in the event of another stimulation.
It is important to note that for many women the sexual desire is a reactive desire, which according to Dr. Basson is not spontaneous and arises as a response to stimulation as soon as the sexual activity begins.
The reason for wanting sex comes from love, sexual attraction and desire for closeness and intimate relations with her partner.
