One common form of lubrication is spit -- it's always in supply. (Except, perhaps, when you start getting really excited and your mouth dries out!) Another method is to masturbate in the shower or bathtub with soap or shampoo. This works okay -- but if any soap gets into the hole at the end of your penis, it really stings! Plus, soap or shampoo can irritate the skin if you do it for a while. Alternatively, petroleum jelly (Vaseline) works, but it's greasy and doesn't allow your hand to move very fast. Baby oil also works, but it's messy to clean up and leaves stains easily. Hand lotion, like Vaseline Intensive Care, is very popular and works well. But perhaps water-based "personal lubricants," like K-Y Jelly and Astroglide, work the best. K-Y Jelly can be found in drugstores or supermarkets, usually near condoms or feminine-protection products; it comes in a form that looks like a tube of toothpaste. These personal lubricants have just the right consistency for great masturbation at any grip or speed, and they clean up easily with a towel.
There is one problem with many water-based lubricants, though: they dry out. If you masturbate for 20 minutes, you have to keep re-applying the lube, and eventually the stuff thickens up into goop. If that starts to happen, put a little spit on your penis, or dribble a few drops of water onto it. That will wake the lube right up, and you'll be at it full-force again! If you really want to be efficient, make a mixture of water and lube and keep it by your bed. Whenever your hand starts to dry out, add some of the mixture. You can masturbate worry-free all night long with this technique! The trick, though, is to make your concoction with just the right combination of water and lube. Too much water and the jelly will start to wash away; two little and it'll eventually start to gunk up.
Some modern personal lubricants are formulated to dry out slower or not at all. For masturbation, this has obvious benefits.
As you get further into your masturbation session and start to get a little more excited, a small amount of fluid (commonly called "pre-cum") might ooze out of the end of your penis. This is normal. Some boys actually get enough "pre-cum" going that they can use it for lubrication.
You may not have a very interesting masturbation session if you just stare at your hand going up and down your penis. Experienced masturbators know it's fun to lie back, close your eyes, and think of sexy things. Your fantasies can have no limits -- anything goes. Even something you would never do or want to do in real life can be something to fantsize about while masturbating. Let your imagination run wild!
Masturbation with the intent to orgasm is about building up the stimulation over time until your body can't take it anymore. A lot of it is mental, though -- you need to concentrate on the feelings you're producing. Close your eyes and think of the sexiest person or situation you can imagine. It helps if this "fantasy" of yours corresponds to the physical feelings you're experiencing -- for example, you can imagine that your super-sexy person is masturbating you. Also, try moving your pelvis around, contracting your butt muscles rhythmically as if you were actually having sex; this helps your body to "get into it."
Remember: If you're still in your early teens, you may be too young to ejaculate. If that's the case, you may still have an orgasm -- but it probably won't be as intense as it will be when you're older. You just have to be patient and wait for your body to develop more.
Your feelings will build more rapidly if you bear down by rhythmically contracting the muscles inside your pelvis -- the same ones that control your bladder. Eventually, as those muscles get stronger (they'll probably be getting plenty of exercise!), you'll develop much better control over them -- but for now, you can use them as a kind of "gas pedal" to make those feelings stronger and stronger.
When you reach the point just before ejaculation, the muscles in your body will start to stiffen up, you'll probably make some funny faces, and then a series of waves of muscle contractions will take over your pelvis. At the same time, it will feel like a lightning bolt of electricity is going through your brain, and every nerve in your body will tingle, alive with energy. You may even cry out or moan involuntarily (something to consider if there are other people in the house). A teaspoon or two of semen -- a thick, whitish fluid that looks a little like salad dressing -- will come out of your penis. It might just dribble out, but if you're a little older (like 14 or 15 or more), it will probably shoot out with some force, perhaps flying a foot or two through the air. Three to eight of these squirts will occur quickly, but you won't care -- you'll be feeling better than you've ever felt before, guaranteed! After five or ten seconds, the semen will stop coming out, and you'll return to earth. Your penis will probably get very sensitive, so you won't want to rub anymore, and you might suddenly become very un-horny. You'll lie there breathing very heavily for a minute or two, your heart pounding.
Congratulations -- you just masturbated for the first time!
Usually, after a male ejaculates, he loses his erection and goes through a period of time when he isn't interested in getting aroused again. In fact, he may be unable to get an erection during this time. However, depending on a number of factors, you might be able to start up again after a few minutes, or even immediately. If you want to and it's convenient, go right ahead! Never let guilty thoughts get in the way of giving yourself pleasure; there's absolutely no reason to have them. Remember -- don't ever stop having fun with your body!
