When it comes to penis fun, a guy knows what to do - and it usually ends with an orgasm. But if knowledge is power, then a man who has a little more knowledge about his orgasms and penis care might have a much better time in bed. Here are a few eye-opening facts about orgasm that a man needs to know for optimum penis fun.

1) Not every guy gets off. Up to 25 percent of all men who engage in sexual activity don’t actually reach orgasm while doing it. However, that number doesn’t say why this happens - it might be anything from being interrupted at an inopportune moment to having trouble with delayed ejaculation. And speaking of ejaculation…

2) Orgasm and ejaculation are not the same thing. Most men believe that the feeling of orgasm and the act of ejaculation are the same thing, as they tend to happen at exactly the same time. However, a man can ejaculate without an orgasm, and vice versa. For most men, orgasm actually happens slightly before ejaculation.

3) Men can have multiple orgasms . If a guy figures out how to have an orgasm but not ejaculate, he can potentially have more than one orgasm. Since ejaculation tends to end the penis fun by deflating the enjoyment, so to speak, an orgasm doesn’t have to lead to a loss of erection. It can take time to figure out how to separate the two, but most men find it worth the trouble.

4) A guy can really get some distance . The longer he waits to ejaculate, the more likely it is that the force behind the semen will be quite powerful. In fact, some men have a recorded, verified "shooting distance" of over 20 feet! Talk about releasing some pressure.

5) Once a man ejaculates, the game doesn’t have to end . Though younger men are notorious for being ready and raring to go only a few minutes after their orgasm, older men tend to take more time to recover. In fact, some men can take up to an hour or more to be ready to go again. The good news is that the healthier a man is, the more likely he will be able to go again soon.

6) Premature ejaculation doesn’t have to be a bad thing . Premature ejaculation is defined as getting off in two minutes or less. However, if that seems to be a problem, a guy can always go for a "quickie" first, then rely on the idea that his second or third round will allow him to last longer.

7) Guys have a special spot, too . Just like a woman’s G-spot, a guy can have the same experience. It happens by massaging the prostate, which can be incredibly pleasurable for a man. Specialized toys can help him reach it if he doesn’t have a partner to help him. Ejaculations and orgasms from stimulating the G-spot are said to be much stronger for a guy than any other type, so it’s worth trying.

If a man wants to stay as healthy as possible, he can make a point of enjoying penis fun at every opportunity, as well as reaching for a powerful penis health crème (health professionals recommend Man 1 Man Oil, which is clinically proven mild and safe for skin). The best penis heath crèmes will include vitamins A, C, D and E for their skin-enhancing elements, as well as amino acids and antioxidants that provide a natural boost to overall penis health. By keeping the penis in great shape at all times, a man can be ready for penis fun no matter when it comes calling.
