Orgasm: All you should know

Orgasm is the pinnacle of sexual satisfaction, which is an intense emotional and physical satisfaction. The issue of orgasm has only been comfortably discussed in recent times, when society has become more open about sex. There is a big difference between orgasm in men and in women.

Orgasm can be defined in different ways based on many different criteria. Medical professionals use physical changes as the basis for their definition, while psychiatrists base their definitions on emotional and reflexive changes. In fact, a single, general definition of orgasm does not exist.

Sexologists define orgasm based on patterns of sexual response. Although the process of orgasm varies greatly between individuals, it is generally possible to build a baseline.
The models below have been developed to describe orgasmic processes that occur in all forms of sexual response and are not limited to vaginal sex alone.
Master and Johnson's four-phase model:
Excitement; Stabilization; Orgasm; Exit. Kaplan's three-phase model: This model differs from most other models of sexual response because it includes desire - something the other models do not cover because it does not change in the genitalia. It is important to emphasize that not all sexual activities are preceded by desire:
Lust; Excited; Orgasm.

A 1997 study suggested that men with high orgasm frequency had a significantly lower risk of death than men with low orgasm frequency. This is contrary to many cultural and religious views that hold that orgasm harms a person's body and behavior.
There is some evidence that frequent ejaculation may reduce the risk of prostate cancer. A team of researchers found a 20% lower risk of prostate cancer in men who ejaculated at least 21 times a month compared with men who ejaculated only 4 to 7 times a month.
Certain hormones released during orgasm such as oxytocin and DHEA have been identified - some studies suggest these hormones may have a protective role against cancer and cardiovascular disease .

There are different types of orgasms:
Combined orgasm: Various types of combined orgasms occur together; Multiple orgasms: A series of short-lived orgasms rather than just one orgasm; Pressure Orgasm: Orgasm comes from indirect stimuli under the effect of pressure. A form of self-stimulation occurs more commonly in children; Relaxed Orgasm : Orgasm is achieved from deep relaxation during sexual arousal; Tension Orgasm: A common form of orgasm achieved from repeated stimulation that causes the body to tense up. There are also other types of orgasm such as:
Fantasy orgasm: Orgasm is achieved entirely from mental stimulation without any other kind of stimulation; G-spot orgasm: During vaginal sex, there is one area that is more sensitive than other areas and gives a different pleasure compared to other areas.

Below is a description of the female orgasm process using Masters and Johnson's four-phase model:
Arousal: When a woman is physically or mentally stimulated, the blood vessels in the genital area dilate. , blood flow is more, vaginal discharge is secreted, the vagina becomes wet and wide. Heart rate, breathing rate, blood pressure increase; Stabilization: When blood flow to the vagina reaches its maximum limit, it becomes firmer. Breasts can increase in size by up to 25%, the clitoris retracting into the pubic bone seems to disappear; Orgasm: The genital muscles twitch rhythmically every 0.8s. Orgasms in women usually last longer than men, with an average length of 13 to 51 seconds. And unlike in men, most women don't have a recovery period, so they can continue to orgasm if aroused again; Relapse: The body gradually returns to normal, the heart rate and breathing rate slow down.

The following description of the male orgasm process uses Masters and Johnson's four-phase model:
Arousal: When a man is physically and mentally stimulated, an erection occurs. Blood flow to the corpus cavernosum increases, the penis becomes larger and harder, the scrotum shrinks causing the testicles to be pulled upward; Stabilization: When the blood vessels in the penis area are filled with blood, the penis and testicles increase in size, the muscles of the buttocks and thighs contract, blood pressure increases, heart rate and breathing rate both increase; Orgasm: The semen is pushed into the urethra and out through the continuous contraction of a series of muscles. The average male orgasm lasts 10 to 30 seconds; Regression: The man temporarily enters a state called the rebound phase, and is unable to have more orgasms at this time. Recovery time varies from person to person, and usually increases with age. The body gradually returns to normal while the heart rate is still fast and the breathing rate will be fast and strong.

There are a number of disorders associated with orgasm, leading to stress, confusion, and shame. Example:
Female Orgasm Disorder: Orgasm dysfunction in females mainly focuses on the delay or failure to reach orgasm despite sufficient stimulation. Failure to orgasm can be primary (a woman who has never had an orgasm), or secondary (a woman who has had an orgasm but cannot now). Orgasm disorders in women can be the result of taking certain medications or mental problems such as anxiety, depression; Orgasm Disorder in Men: Orgasm dysfunction in men is associated with a lack or delay of orgasm that persists or recurs despite adequate stimulation. It can be the result of conditions such as heart disease, mental illness, or certain medications. Premature Ejaculation: Premature ejaculation is closely related to orgasm, which is often caused by both psychological and biological factors.
