Are there biological differences in orgasms attained through intercourse and mastorbation?

In males no there is no biological difference, unless you are stimulating the prostate, in which case the result is the same, but the method is different.  So no matter how you get off, the biological symptoms are the same, spazm and ejaculation.  The factor that makes it seem different is the method and emmotions involved, such as making love vs masterbating.  With women there are two classified types of orgasms, there is the clittoral orgasm, in which an orgasm is achieved by stimulating the clitoris externally.  There is a second type of orgasm, which I have heard called the g-spot orgasm, but I cannot remember the actual name.  It is achieved from stimulating internally near the cervix in the vaginal canal.  I hope this helps, women also have a stronger emmotional aspect attached to sex, so they may be more likely to have intense orgasms associated with sex as opposed to masterbation.

No. Actually, female orgasm increases the likely hood of becoming pregnant.

A woman's orgasm may serve a purpose as far as the reproductive aspect of it goes. It is said that he female orgasm helps to draw sperm up through the cervix and uterus, thus aiding fertilization and reproduction. Fertility specialists sometimes tell women to lie on their backs and masturbate to orgasm after being artificially inseminated. Female orgasm is correlated with higher fertility rates and more babies.\n\nAnd as far as your "why does it happen" question goes, sex and orgasms are pleasurable. regurdless of whether people are married or even capable of procreation. I don't see what "the bible" has to do with this. \n\nPersonally, I'm agnostic, and don't believe in "god" or "the bible".

The feeling of approaching an orgasm is different for each male and is extremely difficult to describe. Certain muscles contract and your brain releases certain hormones, but other than that the feeling is individual (this question is akin to a guy asking a woman how painful childbirth is; there's no way an individual can measure another individual's pain or other physical feelings)

As far as I know, there is no evidence to suggest that there is a correlation between ejaculation and weight gain.  Maybe you like to eat after you orgasm?

Ejaculation, lubrication and orgasm are the correct phases.\n\nAlso it is believed that if you can take advantage of the Gräfenberg spot, or G-spot, you can reach orgasm easier. But it is not scientifically proven.

I guess that your request is connected with your partner satisfaction.\nIn fact, the most part of women need longer times for reaching orgasm than men.\nYou know that the average time is within 15-30 min., but it gets no sense if our partner needs a different time. Therefore, we must compare our time (short or long) with our partner’s one!\nAbout your question, excluding functional diseases, you know that during the sexual act our mind has a relevant duty. Thus, we have to fight against it mainly.\nSome therapist or psychologist put some different methods to follow, and about them, you should buy some specific book.\nI only can give you some advices now.\nTry to begin the full act (penetration) as late as possible using in the meanwhile other methods (FOREPLAY) to excite your partner. While “acting” try to think about different stuffs, just to distract your mind. Somebody stops the act a bit before the apex, just to avoid the forthcoming ejaculation or stopping many times the penetration during the act (continuing to excite the partner anyway).\nThen, if we are able to have two acts consecutively, the most will already be done!

Probably not.  If you consider what an orgasm actually is, then you will understand that you could technically have an orgasm on any part of your body.  Paraplegics often use the ear as a location of having an orgasm.  If you are wondering about the specific anatomy of a human female, then that is debatable.  Most animals only use sex a means of procreation.  However, there are species, besides humans, who have sex for reasons other than procreation.  Is it for pleasure?  Who knows.  But, when your species has a relatively long gestation period, and most females only give birth to one baby at a time, there has to be some incentive to have sex to make sure that the species survives.

Almost always.\n\nHowever, if you do not, I would point out that there is an evolutionary reason for this.\n\nWhen a man ejaculates, his ejaculate forms a pool at the base of the vagina, a woman's orgasm forces the mouth of her cervix into that pool to improve chances of impregnation.\n\nTherefore nature designed it so that men orgasm first.\n\nIf you want to achieve a simultaneous orgasm with your mate, you can do so by practicing, pay close attention to the signs that orgasm is approaching for both of you, and practice making small changes until you are able to achieve it.\n\nIf your wife requires extra stimulation, you may want to introduce the use of a toy into your lovemaking so that she can receive extra clitoral stimulation during the act.

An orgasm is an emotional and physical experience that occurs during a “sexual response cycle”. Before an orgasm, your body becomes increasingly excited. Breathing, heart rate and blood pressure increases. The pupils of the eyes dilate; the lips of the mouth darken, the nipples become erect, the clitoris swells, becomes hard and exposed, (much like the aroused penis). With increased excitement, the skin becomes flushed and it begins to sweat.\n\nIn women, the labia, clitoris, vagina and pelvic organs enlarge in very much the same way as the aroused penis enlarges. Sometimes there is a plateau of excitement which is held for several minutes before you are about to orgasm.\n\nOrgasm is the point at which all the tension is suddenly released in a series of involuntary and pleasurable muscular contractions that may be felt in the vagina and/or uterus (some women do experience orgasms without contractions).\n\nThe orgasm happens when excitement seems to go over the edge -- a climax or crescendo is reached which may last several seconds or longer. During orgasm the body stiffens and the muscles contract. Involuntary muscle contractions and spasms may occur in various parts of the body, including your legs, stomach, arms, and back. The muscles of the vagina relax and contract rapidly, as do the muscles of the uterus. The glands of the vagina (Bartholin's glands) discharge a watery secretion, which acts to lubricate the vagina.\n\nThe main physical changes that occur during a sexual experience are a result of vasocongestion. This is the accumulation of blood in various parts of the body. Muscular tension increases and other changes occur throughout your body also.

Abstinence has no harmful effects on your body, however sexual activity has benefits.\nFrequent ejaculation, regardless of whether it's with another person or not, has been shown to help reduce the risk of prostrate cancer.  Orgasm achieved by mastrubation is also beneficial in relieving stress.\nThe only real benefit in sexual intercourse with another person (as opposed to solo mastrubation) is the exercise gained by the vigor of the act.

It might just be the intimacy that satisfies you. You can have great sex without an orgasm. Who ever tells you different obviously doesn't know the meaning of intimate feelings. Of course its always great to orgasm, once in a while great sex without one is OK.

The nipples of some women are extremely sensitive to touch.  However, it is because most women do NOT achieve orgasm by manipulation of the breasts, it is more frequently, a method of foreplay rather than a basic method of sexual gratification.  The clitoris is very similar during  intercourse to the penis.  Without clitoral stimulation, there is seldom intense orgasm or no orgasm at all.

I would be inclined to say that with the right external factors, a female could orgasm continuously, or repeatedly at very short (30 second) intervals for the entire 24-hour period.  The length of time it takes for a male to be able to become erect and ejaculate is highly dependent on his age.

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?

It's all a matter of personal preference.  I don't beleive that there's a difference between lesbian and non-lesbian masterbatory amounts.  It varies from person to person.  Also the influence of religion and family might sway the tendency to masterbate.  It's a perfectly natural thing to do for every mammal.
