Scientifically speaking, what is an orgasm and why does it feel good?
372264
Stimulation of the very sensitive nerves of the genitals, combined with the desire to be doing this (rape is a turn off, despite genital stimulation), allows all kinds of endorphins and dopamine and adrenaline to flood the brain. These chemicals bind to the pleasure receptors in the brain, and the result is a feeling of pleasure. Taken far enough, the entire nervous system has a spasm, the brain especially. Orgasm takes place in the brain, not in the genitals.\nOrgasm serves several biological and social purposes. It reinforces the desire to do it again, so that pregnancy can result. It also binds people together (makes couples out of people)so that families can form. It also makes life bearable - can you imagine going through a life in which you never have an orgasm? It would be pretty dreary.

The reason sex feels so good is in the process the brain releases chemcials that cause intense pleasure in the brain. Examples of these chemicals are dopamine and adrenaline to name a few. Dopamine is also a natural pain killer in the humain body and if my memory severs me right thats what causes intence pleasure.

From my experience, 5 to 20 seconds, Bonita. However, many women can have multiple orgasms, usually a few minutes apart.\n\nWhat I've been told directly is that they feel: wonderful, heavenly, hot, wild, creamy, delightful, and many other superlatives. Very much the way a man would describe an orgasm.

Orgasms\n\nMost Orgasms\nFor 22 years, Doctors William Hartman and Marilyn Fithian of the Center for Marital and Sexual Studies in Long Beach , California , have been faithfully recording the orgasmic response in their laboratory. After hooking up subjects to blood-pressure and heart-rate monitors and various sensors in the vagina or anus, the doctors would sit by the beside and take copious notes as the subjects busied themselves. In an attempt to head off accusations of prurience, they say such research is stupifyingly dull, saying they had to "struggle to stay awake." However, they overcame the tedium to spend 10,000 hours in the laboratory. After several false starts (originally they had the subjects push a button whenever they had a orgasm, but during the heat of the moment they usually became too preoccupied to be concerned with the cause of research), the study continued apace, eventually encompassing 751 individuals. The most orgasms they recorded in an hour for a woman is a staggering 134, while the best men could do was 16. How we lesser mortals can hope to achieve anything in that vicinity was not discussed.\n\nLongest Orgasm\nMale Yet another example of inequality in the sexes. The typical male orgasm lasts anywhere from 3 to 8 seconds, though its possible through deep breathing and regular exercising to extend it to…oh, maybe 10 seconds or so. Pitiful, you may think, compared to the Herculean orgasms accomplished by some women, but sex is usually measured in terms of satisfaction of the male; in fact, the anthropologist Margaret Mead uncovered societies in which the female orgasm is unknown. So I guess it all evens out in the end.\n\nFemale As you probably know, women are capable of multiple orgasms without having to rest between. However, as fellow savant Cecil Adams expounds in his book More of the Straight Dope, women are capable of so much more:\n\nWhat you probably didn’t know is that women are capable of sustained orgasm, called status orgasmus. These start with a 2 to 4 second "spastic contraction" and last twenty to sixty seconds. Masters and Johnson (1966) published a chart of one woman who experienced a 43-second orgasm, consisting of at least 25 successive contractions. Status orgasmus is usually the result of self-stimulation, but a woman can experience it at the hands (or whatever) of a suitably skilled lover.\n\nFastest Orgasm\nMale Certain rare individuals—1 in every 1250 men, to be precise—can ejaculate by deliberately concentration on sexual fantasies without any genital manipulation whatsoever, for a total time to orgasm to be…well, right around zero seconds. As Kinsey put it: "In such a case the psychic stimulation is entirely responsible for the result." Truly, the mind really is the most powerful sex organ.\n\nFemale In his book, Dr. Kinsey & The Institute for Sex Research, Wardell B. Pomeroy recounts the case of one extraordinary woman who had near-godlike powers in the sack. His words: "I remember one woman who was capable of from fifteen to twenty orgasms in twenty minutes. Even the most casual contact could arouse a sexual response in her. Observing her both in masturbation and in sexual intercourse, we found that in intercourse her first orgasm occurred with two to five seconds after entry." [My emphasis] Ladies, eat your hearts out.\n\nLargest Ejaculate Volume\nBesides us, who else would be concerned about ejaculate volume? Why, fertility experts, of course. If ever in the vicinity of a large library you might want to dig out a fun article entitled "The semen of fertile men: statistical analysis of 1300 men," by Aquiles J. Sombrero, MD et. al. and published in The Journal of Fertility and Sterility. The data were collected from an outfit that performs vasectomies. Prior to vasectomy each man was required to submit a specimen in a special container, on which was recorded the time of collection and the duration of abstinence prior

Masturbation is the manual excitation of the sexual organs, most often to the point of orgasm. It can refer to excitation either by oneself or by another (see mutual masturbation), but commonly refers to such activities performed alone. It is part of a larger set of activities known as autoeroticism, which also includes the use of sex toys and non-genital stimulation.

myths such as this were common in medical literature 100 years ago.  now its thought that orgasm (which can be achieved via masturbation) can enhance the immune system.  These myths were rooted more in religious and cultural ideology than in any kind of scientific study.  \nhuman brains are hardwired to enjoy sex, alone or with others.  How else would have our species survived?

Besides masturbation material, it stimulates the brain in addition to physical stimuli (sort of like a double dose of adrenaline).  It will stimulate enough that the pleasure from orgasm is a bit more intense.  Which is why some guys become addicted to it, literally, they can not climax without it.   All things in moderation, huh?

Your mental attitude about it. Both are there to send your mind a message ... "i like what i am experiencing now"(pleasure) or "something is wrong, tell me what it is"(pain). Interestingly, for some people the exact same sensation can be both at different times.

Orgasm is the peak of sexual excitement...followed by a release of sexual tension and rythhmic contractions of pelvic reproductive organs. in females it consists of contractions of lower 1/3 of vagina, uterus and cervix; increased heart rate, pulse rate and blood pressure accompany it. the duration lasts from 3-15 secs.

Because having your prostrate 'massaged' is thrilling. My boyfriend is abottom and he orgasms without toughing himself, he does so at the exact moment that I do, and I can FEEL him throbbing inside against my 'head' while Im orgasming.

It's very possible.  Orgasms are due to firing of synapses in the brain and are usually caused by stimulation, but don't have to be.  It's very possible to have spontaneous orgasms, though it's rare.
