How Female Sexual Arousal Works in scientifical way

The female sexual response is dependant on what goes on in the mind and body. Several systems in the body are involved including the nervous, endocrine or hormonal, cardiovascular, respiratory, and of course the reproductive system. There are five stages of arousal that are associated with physiological and psychological changes; desire, excitement, plateau, orgasm, and resolution.

Stage 1: Desire

The first stage is desire, which stimulates sexual excitement and sexual activity. Desire occurs in our minds and bodies when responding sexually to a variety of stimuli including sight, sound, smell, touch, taste, movement, fantasy, and memory. These stimuli can create a strong wanting for sexual stimulation. Societal and cultural values influence the range of stimuli that provoke sexual desire, and ideals about the stimuli considered "sexual" or "attractive" can vary greatly between cultures and among subsets of a single culture. In addition, each individual reacts to sets of stimuli that are based on his or her own thoughts, feelings, and experiences.

Stage 2: Excitement

The second stage is excitement, which is the body's physical response to the stimuli during the desire phase. The excitement stage, for some women, may be achieved with very little physical or mental stimulation. However, other women may require significant intimacy, physical stimulation, or fantasy because it can take longer for them to achieve full arousal. Induced by emotional changes, the excitement stage typically includes: an increase in heart rate, blood pressure, and respiration; breasts increase in size and the nipples become erect; the vagina lengthens and widens; the clitoris swells and enlarges; the labia swell and separate; the vagina becomes lubricated; and the uterus rises slightly while the uterine and cervical glands secrete mucus to lubricate the vagina. With the increase of blood flow, a woman will experience heightened sensitivity as the vaginal swelling and lubrication occurs. Vaginal lubrication is the key indicator of sexual excitement.

Stage 3: Plateau

The third stage is called plateau. It is the highest moment of sexual excitement before the fourth stage, which is called orgasm. As long as physical or mental stimulation continues during full arousal, the plateau stage can be achieved. This stage can be achieved, lost, and regained several times without the occurrence of orgasm with the following physiological changes: heart rate and breathing rate further increase; blood pressure rises even more; muscle tension increases; the clitoris withdraws; the Bartholin's glands lubricate; the areolae around the nipples become larger; the labia continues to swell; the uterus tips to stand high in the abdomen; and the lower vagina swells, narrows and tightens.

Stage 4: Orgasm

The fourth stage is orgasm, which occurs at the peak of the plateau stage. At the moment of orgasm, the sexual tension that has been building throughout the body is released, and the body releases chemicals called endorphins, which causes a sense of well-being. The intensity of an orgasm(s) can vary among women and varies from one sexual experience to another. Orgasm may involve intense spasm and loss of awareness, or it may be signaled by as little as a sigh or subtle relaxation. Women are capable of having multiple orgasms, which means moving immediately from orgasm back into the plateau stage and back to the orgasm stage again. During this stage the heart rate, breathing, and blood pressure all reach their highest peak. Also, there is a loss of muscle control or spasms that involve synchronized contractions of the vaginal and abdominal muscles that, when released with endorphins, cause extremely intense pleasure. The uterus, vagina, anus, and other pelvic muscles contract five to twelve times at 0.8-second intervals.

Stage 5: Resolution

The final phase, after the orgasm stage, is called resolution. During this stage, the heart rate and blood pressure slow below normal but then return to normal soon afterward. As the blood flows away from the vagina, blood vessels dilate to drain the pelvic tissues. The breasts and areolae shrink in size and the nipples lose their erection. The clitoris resumes its position prior to arousal and shrinks slightly. The labia returns to normal size and position, the vagina relaxes, the cervix opens to help semen travel up into the uterus but then closes approximately 20 - 30 minutes after orgasm and the uterus lowers into the upper vagina region. As everything gets back to its pre-arousal state, there is a loss of muscle tension and an increase in relaxation and drowsiness.

men dont understand really

A woman was in a coma. She had been in it for months. Nurses were in her
room giving her a bed bath. One of them was washing her private area and
noticed that there was a slight response on the monitor when she touched
her. They tried it again and sure enough there was sizable movement.*

They went to her husband and explained what happened, telling him, as
crazy as this sounds, maybe a little "0ral sex" will do the trick &
bring her out of the coma."

The husband was skeptical, but they assured him that they would close
the curtains for privacy.

The husband finally agreed and went into his wife's room. After a few
minutes the woman's monitor flat lined, no pulse, no heart rate. The
nurses run back into the room. "What happened!?" they cried.

The husband said, "I'm not sure; maybe she choked

Result oriented man

Doc, you've gotta help me! My wife just isn't interested in sex anymore. Haven't you got a pill or something I can give her?"

"Look, I can't prescribe..."

"Doc, we've been friends for years. Have you ever seen me this upset? I'm desperate! I can't think; I can't concentrate; my life is going utterly to hell! You've got to help me."

The doctor opens his desk drawer and removes a small bottle of pills. "Ordinarily, I wouldn't do this. These are experimental; the tests so far indicate that they're VERY powerful. Don't give her more than ONE, understand? Just ONE."

"I don't know, doc. She's awfully cold."

"One. No more. In her coffee. Okay?"

"Um... okay."

He thanks the doc and heads for home where his wife has dinner waiting. When dinner is finished, she goes to the kitchen to bring dessert. In fumbling haste, pulls the pills from his pocket and drops one into his wife's coffee. He thinks for a moment, hesitates, then drops in a second pill. And then he begins to worry. The doctor did say they were powerful.

Then an inspiration strikes... he drops one pill into his own coffee. His wife returns and they enjoy their dessert and coffee. Sure enough, a few minutes after they finish, his wife shudders a little, sighs deeply and heavily, and a strange look enters her eyes. In a near-whisper and in a tone of voice he has never heard her use before, she says, "I need a man..."

His eyes glitter, and his hands tremble as he replies, "Me too

Sex good for Health


Maintaining Ideal Body Weight

There are 3500 calories in a pound of fat. For every 3500 calories you burn (that you do not replace with food!) you will lose one pound of fat. Sexual intercourse burns approximately 150 calories per half hour. Here's how that stacks up against some other activities that may be part of your fitness regime: yoga 114 calories per half hour, dancing - rock 129, walking - 3mph 153, weight training 153, canoeing - 2mph 153, volleyball 174.

According to one survey reported by the Ottawa Citizen, Canadians on average have sex 7.33 times per month, lasting approximately 24.4 minutes. That means that "Joe Canada" is burning off more than 10 thousand calories a year, or about 3 pounds, in a not particularly active sex life. Those who are more sexually active, into Tantra for instance where lovemaking lasts 4 hours, would burn up 600 calories a session. At once a week that's 31,200 calories or 9 pounds per year. Considering that people put weight on gradually, slowly gaining 5-10 pounds per year until they are overweight, it's not unrealistic to assume that regular sexual activity is one way to help maintain a healthy body weight.

Increased Blood Flow

Sex helps increase the blood flow to your brain and to all other organs of your body. Increased heart rate and deep breathing accounts for the improvement in circulation. As fresh blood supply arrives, your cells, organs and muscles are saturated with fresh oxygen and hormones, and as the used blood is removed, you also remove waste products that cause fatigue and even illness..

Lower Cholesterol

Lowering your cholesterol is another of the "sex as exercise" benefits. Sex helps lower the overall cholesterol level. Perhaps more importantly it tips the HDL/LDL (good/bad) cholesterol balance towards the healthier HDL side.

Stress Reduction, Relaxation and Improved Sleep

People having frequent sex often report that they handle stress better, so the normal stresses of living do not become distress. The profound relaxation that typically follows lovemaking, with orgasm for women and ejaculation and/or orgasm for men, may be one of the few times people actually allow themselves to completely let go, surrender and relax. Many indicate that they sleep more deeply and restfully after satisfying lovemaking. In the relaxing afterglow you may be able to let go of distracting thoughts. Being able to stop thinking has helped many to overcome insomnia.

Sex as Pain Reliever

Through the touch magic of sex the hormone oxytocin is secreted in your body which in turn causes the release of endorphins. Because of these natural opiates sex acts as a powerful analgesic, elevating the pain threshold and helping to relieve the aches of conditions like arthritis, whiplash and headaches. Now there's a novel approach, sex as a remedy for headache rather than an excuse for abstaining!

With arousal and orgasm oxytocin levels rise. They spike 3 to 5 times higher than usual just before orgasm. In fact it is oxytocin that triggers the orgasm. Measurements performed at the Masters and Johnson laboratories have shown that the uterine contractions brought about by orgasm (triggered by oxytocin) are just as powerful as those of child labor. Women can use this extraordinary orgasmic contraction and relaxation of the uterine muscle to relieve cramps during PMS and menstruation.

Live Longer, Stay Younger

A British study of 1,000 men found those who had at least two orgasms a week had half the death rate of their countrymen who indulge less than once a month.

The hormone DHEA promotes sexual excitement and increases in response to it. Dr Theresa Crenshaw author of The Alchemy of Love and Lust says DHEA may be the most powerful chemical in our personal world. It helps balance the immune system, improves cognition, promotes bone growth, and maintains and repairs tissues, keeping your skin healthy and supple. It may also contribute to cardiovascular health and even function as antidepressant.

Prostate and Genital Health

Some doctors believe that more than 75% of men over 50 have a somewhat enlarged prostate, and that virtually all men will suffer from prostate enlargement if they live long enough. This condition, called benign prostate hypertrophy (BPH), is normal and usually not dangerous. Unfortunately, some of these men develop prostate cancer, one of the leading causes of death in older men. Regular sexual intercourse with frequent ejaculations will help to keep the prostate healthy.

For those men who practice delaying ejaculation, for example in the practice of Tantra Sacred Sex, performing Kegel exercises (in which you contract the muscles around your genitals), will tone these muscles, just as exercising other muscles tones other areas of your body. More importantly, these exercises will help keep the prostate healthy, by moving the sexual energy up out of the prostate and circulating it throughout your body. The technique is very simple and you can perform hundreds of contractions per day for top sexual/physical fitness for both men and women. Imagine you are urinating, but want to stop the flow of urine, that's all there is to it.

Contracting your muscles in this way is one of the healthiest exercises you could add to your exercise regime. When 178 Belgian men with minor erection problems participated in a 4-month daily rehabilitation program which primarily focused on Kegel exercises, 74 percent showed improvement and 43 percent were cured. For women, Kegels strengthen the entire urogenital tract, aiding greatly in childbirth and preventing the onset of incontinence in later life. They also sensitize the genital tissues, helping women to become orgasmic and/or increase the intensity of their orgasms

Boost Testosterone and Estrogen

Regular sexual activity boosts testosterone and estrogen levels in both men and women. Besides boosting your libido testosterone fortifies bones and muscles. Some physicians suggest that testosterone keeps hearts healthy and good cholesterol high. Testosterone is what makes the sex drive in men and women more aggressive. It makes you want to have sex, pursue sex, initiate sex and perhaps dominate the lovemaking. Testosterone seems to motivate both men and women to strongly desire specific genital sex and release by orgasm. Because men have so much testosterone, they seem obsessed with genitals, intercourse and ejaculation, but appear to care less for romance and foreplay-touching, hugging, cuddling, eye gazing, etc..

Sex increases women's estrogen levels keeping vaginal tissues more supple and also protecting against heart disease. It is estrogen that makes a woman sexually receptive and responsive to a man's approach. It is estrogen that makes her want to be touched and feel romantic, it is testosterone that makes her want to be penetrated. Estrogen makes a woman soft-breasts develop in response to estrogen. Estrogen is a powerful influence on how a woman smells. It influences the degree to which she projects softness, openness, and interest in sexual touching.

Men's bodies also produce estrogen. In fact testosterone can be converted into estrogen in the man's body. Some estrogen helps a man to develop the softer, more nurturing feminine sides of their personalities. As men age, the testosterone/ estrogen balance begins to shift, with testosterone decreasing and estrogen increasing, and this is one reason why so many men seem to mellow out as they get older.

The Healing Power of Intimacy

Sex is good for you, but sex with love is even better. According to Dr. Dean Ornish author of 'Love and Survival: the Scientific Basis for the Healing Power of Intimacy', "an open heart can lead to the most joyful and ecstatic sex". His researches into intimacy and its effects on health have shown that "anything that promotes feelings of love and intimacy is healing". If you have someone who really cares for you and for whom you care in return, someone you are intimately connected with in all ways - emotional, physical and more -- then you may be three to five times less likely at risk of premature death and disease from all causes.

Part of this has to do with the positive effects of touch, what Dr. Crenshaw refers to as Vitamin T. The chemical composition of your body is changed by touch. Caressing, hugging, stroking, cuddling send a chain reaction of chemicals to signal your brain that this is pleasurable, nurturing, good.

There is strong scientific evidence demonstrating the importance of touch to good health. In the 1930s, Dr. Rene Spitz, attending physician at a number of nurseries, noticed that the illness and mortality rates were quite a bit higher in some of the nurseries. His observations and experiments led to the finding that the children who were becoming ill and dying had nothing to do with hygiene or nutrition, but rather had to do with the amount of touching the infants received from the attending staff. He confirmed his findings by hiring "grandmothers" to come into the nurseries to hold, fondle, and cuddle the children. The illness and mortality rates declined rapidly.

Researchers at Miami's Touch Research Institute (TRI) found that premature infants who received three massages a day over 10 days gained 47 percent more weight than preemies who weren't massaged. David Sebringsil, who writes regularly for The Society For Human Sexuality (one of the best online sources of excellent, sex-positive information) , recommends Erotic Massage become a part of or alternative to regular lovemaking. It is one of the best ways to help someone achieve extended, multiple, or "whole body" orgasmic states. Through erotic massage partners learn to give and receive loving touch and extraordinary pleasure. It makes you healthier and happier

Little jhonny

The teacher at the beginning of the class says, "OK kids, we are going to talk about sexual education today. First we'll talk about how the human reproduction goes on..."
Immediately, little Johnny raises his hand, and desperately tries to get the teacher's attention. But the teacher, knowing how little Johnny is about these things, goes on...
"... First, a man a woman have to be in love... " But little Johnny keeps his hand up, waving it up and down, and from one side to the other one.
The teacher ignores him.."..They have to be very much in love because..."
But now little Johnny even starts making noise with his feet, so the teacher decides to acknowledge him.
" OK! Little Johnny. What do you want to say?"
Little Johnny then stands up, and says, "I just wanted to ask. Those of us who have fucked already, can we leave?"

Increasing petrol sales

A petrol station owner in Ludhiana was trying to increase his sales. So, he put up a sign that read, 'Free Sex with Fill-Up.'

Soon a Sardar pulled in, filled his tank and asked for his free sex. The owner told him to pick a number from 1 to 10. If he guessed correctly, he would get his free sex. the Sardar guessed 8, and the proprietor said, 'You were close. The number was 7. Sorry. No sex this time.'

A week later, the Sardar, along with his friend ,a Gujju, pulled in for another fill-up. Again he asked for his free sex. The proprietor again gave him the same story, and asked him to guess the correct number. the Sardar guessed 2 this time. The proprietor said, 'Sorry, it was 3. You were close, but no free sex this time.'

As they were driving away, the Gujju said to the Sardar, 'I think that game is rigged and he doesn't really give away free sex.'
he Sardar replied, 'No it ain't, . It's not rigged at all. My wife won twice last week.
