Not only men, scientists say sex is also an enjoyable experience for most women. But not many people know exactly why the body feels excited during sex.

Scientists say that there are many mechanisms going on in the body that make you feel excited during sex. Each person will experience a wide range of emotions and physical pleasures.
The sexual response cycle consists of 4 phases:
Stimulation Arousal Orgasm Relaxation. Both men and women, both actual intercourse or masturbation go through the above 4 stages. However, the duration and intensity of each phase is different for each person.
Stage 1: Arousal You and your partner can feel:
Increased tension in the muscles Increase heart rate and breathing rate Red skinned nipples Erection Increased blood flow to the genitals: Causes swelling in the vagina penis and labia in women, or erection of penis in men Increased moisture in the vagina Women's breasts are fuller Swelling of vaginal walls in women, or testes in men Scrotum of men Retrieve Lubricating fluid secretion from the male penis

Stage 3: Orgasm You and your partner may feel:
Uncontrollable muscle spasms Intensity of blood pressure, heart rate, and breathing rate peaking Rapidly absorbing oxygen into the body Muscle spasms may occur A sudden and intense release of sexual desire Vaginal muscle contractions and rhythmic contractions in the uterus Rhythmic contractions of the muscles at the base of the penis, resulting in ejaculation Flushing or “skin rash” chicken" all over the body. Women can achieve several more orgasms with continued stimulation. Meanwhile, men have to rest and wait for a while before they can have a second orgasm. This waiting time will vary from person to person and increases with age.

Stage 4: Relaxation During this phase, both partners will:
The body returns to normal function Swollen and erect parts return to their original size and color Have a feeling of well-being, attachment and increased fatigue.

According to experts, the feeling of increased excitement when falling in love is caused by the body releasing neurotransmitters and hormones, which bring pleasure, satisfaction and satisfaction. In other words, excitement hormones and neurotransmitters are the factors that help couples have feelings of sublimation, happiness and extreme excitement when making love. These include:
2.1. Endorphins are neurotransmitters that are released during sexual activity, exercise, or when feeling happy. Endorphins bind to pain receptors in the brain, helping to reduce pain, stress, fatigue, and negative thoughts. Endorphins also calm the central nervous system, creating pleasure and satisfaction. However, Endorphins can cause drowsiness and mild dizziness. Therefore, most men after sex often fall asleep for a short time.
2.2. Oxytocin Called various names, like the euphoria/love/cuddle hormone, the body releases Oxytocin during the climax and promotes a stronger orgasm. In addition, this hormone also creates a desire to be close, caress and make love with your partner.

2.3. Adrenaline During sex, the adrenal gland will release adrenaline, affecting the sympathetic nervous system, dilating the arteries, increasing the force of the heart's contraction and promoting blood circulation to the muscles. Adrenaline levels tend to increase gradually with each stage in the sexual response cycle. So at the climax and climax, you will clearly feel the heart rate and blood pressure increase significantly. In addition, Adrenaline also creates a feeling of love for life and increases excitement when in love, accelerating the pace of relationships and raising emotions to climax.
2.4. Serotonin Serotonin is released after orgasm. This neurotransmitter has mood-regulating and anti-depressant effects. Once released, serotonin will make you feel fulfilled, satisfied, and happy.

2.5. Prolactin This hormone is normally released in the mother after birth to stimulate the mammary glands to produce milk. Besides, this prolactin is also released after both men and women "climax", creating a feeling of extreme happiness. This feeling helps dispel fatigue, stress, and create excitement in daily work. This is also the reason why people with a satisfying sex life are often optimistic, love life, work well, full of energy, and rarely suffer from prolonged stress.

The brain is the main pleasure center during sex. Just being intimate with the right people, your brain increases levels of the cuddle hormone oxytocin, making you feel happy and secure. Scientists know that certain parts of the brain, involved in pleasure, are activated after sex.
During sex, the physical signals that the body perceives are transmitted through the nerves to the brain. The center of the brain will respond by releasing chemicals that make us excited when in love.
Several studies show that the rhythmic nature of the act of intercourse, along with sexual arousal, provides both psychological and physical arousal. As physical pleasure increases during orgasm, so does psychological pleasure. Similarly, more psychological pleasure will increase physical pleasure.
Research also shows that the rhythm of intercourse can help women and men choose the right sexual partner. The movements that work together in harmony are a measure of the quality of sex. One person will tend to stick with the partner that suits them best and gives both of them satisfaction.
