why do males ejaculate when they have sex?

The biological reason is so that they can spread their gametes to the female in order to get a fertilized egg, which is useful for reproducing.

There may be a medical problem and it's always best to see the doctor as early as possible.  But in general, as men age it takes them longer to ejaculate and they don't recover as quickly.\n\nTo shorten the process, you might want to try finishing him with a hand job.  Use a lubricant and he shouldn't complain.

the testicles are on the outside to keep them at a cooler temperature so the body heat doesnt kill them...but i guess if a man ejaculates and he's cold or he's outside and its cold, his sperm could be cold too.

Only men ejaculate semen, but women do have lubrication which is produced by glands near the vaginal opening.

your testes are constantly craking out sperm.  The sperm are stored in the top of your testes to mature (grow)\n\nafter you ejaculate, the sperm is gone, but your testes will produce more.

Most men shudder when ejaculating, particularly when having sex with someone else as the sensations are usually a lot stronger than stimulating yourself by masturbating. It is nothing to worry about. Just enjoy the strong sensations.

You are normal, and like the other answers have said you are in the minority. It is called female ejaculation. It is rare, but normal. You are fine, and yeah, guys do like it. So just relax, and now that  it is fine to be in the minority.

Well.well, maybe time to come out of closet, I ejaculate like I'm peeing but it's not, just like you guys we can cum just as much if not more than you do....\nI have never thought it strange cos all my life (sexual) it has happened , funny tho cos partners have asked if I had wet myself LOL, I call it being a healthy robust woman who has great orgasms...so there is a bit of  trivial info ..LOL

A man's ejaculate contains millions of sperm. The exact number depends on the individual. Sperm is constantly produced so as to replenish the supply after ejaculation.

Not having sex is one factor.\n\nThe other is it seems the body has a sense of when it needs to ejaculate and when it doesn't. When having sex with a monogomous partner, the ejaculate will be less than if having an affair.\n\nThere is no known reason why.

I have seen a few male ejaculations in my life.  Don't worry -- it doesn't always 'shoot out', and it doesn't mean anything is wrong if it doesn't.  Think of the male organs as a pumping mechanism, where a better orgasm will produce more high flying results.  Otherwise, it does kind of dribble out, as you describe.

It can. Even before you ejaculate, sperm are traveling up the tube and some will get mixed in with the precum (which works as a lubricant.) If you are unlucky enough, it could cause pregnancy.

That is when you ejaculate before you are in the women.  it can happen if you are nervous or inexperienced.

of course it flows out. it's supposed to. its not just supposed to stay there. and with your wife feeling the semen inside of her, she doesn't necessarily have to. as soon as you ejaculate, the sperm is deposited into the vagina and then the rest of the seminal fluid flows back out.

The organ involved in male ejaculation is the prostrate, which can be stimulated by anal play for men (about four inches in, curve towards his front, but use *lots* of lube!). It develops from the same cells which, in a female foetus, develop into the G-spot, we think.\n\nBeing open to this does *not* make a man gay, and not all gay men enjoy anal play or penetration. There are many nerve endings around the anus and, if people are open-minded enough to try, then they can find play there very enjoyable.\n\nIf you want to indulge him, try playing after he's showered, with plenty of lube, gentle at first, and see if you get into it. Some women do. The good sex sites (Good Vibrations, Scarlet Letters and Toys in Babeland for example) will have information if you want it.

Premature ejaculation \n \n\n \nWhat is it?\n\nPremature ejaculation (PE) means 'coming too quickly'. \n\nIt's one of the commonest of all sexual problems. Recently, we did a survey of several thousand British males, and approximately 10 per cent of them said that they 'often' or 'sometimes' had this trouble.\n\nWe found that it's commoner in younger men - which is not surprising, as there's a distinct tendency for it to improve with age. Men generally get better control as they grow older.\n\nHowever, a 2004 survey in Europe showed that middle-aged men still have this problem. \n\nFortunately, good treatments are available.\n\nDoes it matter? \n\nWell, in most cases it does matter - because it makes people unhappy and frustrated. And in severe cases PE can threaten or even ruin a marriage - simply because it spoils the sex lives of both partners. Sometimes, the condition is so bad that the man cannot even manage to have intercourse because he invariably ejaculates before he can get into the vagina. This can be devastating for a man's self-confidence. And it can be hugely frustrating and annoying for his partner, too.\n\nHowever, most men merely find PE a considerable irritation - a condition that makes them 'come' very soon after they enter their partners (say, after only one to two minutes), so that neither party gets a lot of satisfaction.\n\nWhat causes it?\n\nFor many years, sex experts have tended to say that premature ejaculation is caused by early 'conditioning'. In other words, the man's early, rushed (and perhaps furtive) sexual experiences had to be quick - so as to avoid detection! The idea is that all this hectic rush 'conditions' him to climax as quickly as possible.\n\nHowever, in our own surveys we have found that many men with PE say that they did not have rushed, hasty early sexual experiences (though others say they did). These maintain that they were 'highly triggered' right from the start of their sex lives.\n\nIt's worth noting that from an evolutionary point of view, it's probable that throughout human history, males who climaxed quickly were more likely to have children. (In other words, if you were a caveman who 'came' very fast, you'd stand more chance of impregnating cavewomen - and, therefore, enlarging and strengthening your tribe - than a chap who took all day about it.)\n\nTherefore, we feel that the tendency to reach orgasm quickly may often actually be inherited rather than learned.\n\nFinally, there's no question that anxiety (or 'nerves') plays a part in many cases of PE. If you're nervous, you're likely to come too quickly. That's why many males have discovered for themselves that a small amount of alcohol eases their nerves and makes them less likely to climax prematurely. But we wouldn't recommend alcohol as a treatment!\n\nTreatment\n\nSo, what can be done for PE?\n\n\n(i) Very mild cases\n\nIf you have very mild PE (for instance, if you can 'last' a good five minutes but would like to last 10), there's probably no point in going to a doctor. Why? Because you should be able to improve matters by simple 'distraction techniques'. This means turning your mind to something else when you sense that a climax is near. For instance, you can:\n\n\nthink very hard about something totally unconcerned with sex. \n\n\npinch yourself hard. \n\n\nbite the pillow. \n\n\nSome men try to treat themselves with a local anaesthetic gel. This product is advertised to the public as a good way to 'damp down' sexual sensation in the penis. But we do not advise using it firstly, because the local anaesthetic can 'dull' the sex sensation for the partner, and secondly because it can sometimes cause a distressing skin sensitivity reaction.\n\n\n\n\n(ii) Getting help for more severe cases\n\n\nIf PE is causing you more significant problems, it is best to consul
