Basic Technique
Masturbation for guys is nowhere near as fraught with difficulty as it is for girls. You have the luxury of being able to pretty much whip it out and jerk off anywhere you'd like (legally, of course).
To begin with, you may wish to use some form of lubrication. Though not all guys do, for some it just works better if they have something to make the penis slippery. You can use items like baby oil, lotion, even soapy water to facilitate the sliding of your hand up and down the shaft of your cock.
Wrap your hand around your cock and move it up and down, varying the speed from time to time. You can start off slowly, and allow the speed to build up gradually, and then slow down again. The is basically a personal preference thing - as you become more experienced with it, you'll develop a rhythm that you like and that works best for you.
For most guys the head of the penis (the glans and frenulum) is the most sensitive, and you may wish to focus solely on it from time to time.
Play with your nut sack (the scrotum). Don't get too vigorous with it or you might hurt yourself - a pain in the nuts as it were.
You may wish to explore your anus. This area is rich in nerve endings and is interconnected with the muscles that provide you with your orgasm. Stimulation of your anus during an orgasm can increase the intensity of your orgasm significantly. Some guys seem to think that, by playing with your ass you may "turn gay" or some other silliness such as that. Anal play is a perfectly acceptable thing to do regardless of your gender or sexual orientation. There's no "magic button" back there that automatically makes you gay if you touch it (and even if there were, there's nothing wrong with being gay).
You may wish to consider "humping" a pillow, the bed, a couch arm or any one of a number of other things. Basically, anything you can do to stimulate your cock to get you off is fair game for masturbation (again, so long as it is legal).
If you're doing it correctly, the act of rubbing your penis will make you more and more excited, like a runaway train speeding down a hill. As you think a particularly sexy thought or play out a sexual fantasy in your mind, you will begin to get a hot feeling inside your pelvis, which will increase in intensity. It may feel like you're about to urinate — but don't worry, that's just the feeling of semen beginning to enter your urethra (the tube that runs through your penis).
As you approach orgasm, you'll feel like you're going over the top of a hill on a roller coaster. Your body will stiffen up, you'll make some weird contorted faces, and you'll begin to feel the orgasmic waves (muscular contractions) deep inside your pelvis. These will quickly push their way up through your cock, and you'll ejaculate a teaspoon or two of a white, milky looking substance. This is the semen that is responsible for impregnating a female. It may shoot out with tremendous force, or it may just dribble out - a lot of that will depend on how aroused you are at the time, and how much build up you've had before you cum. You'll have between 3 and 10 squirts, and then you'll comeback down off that orgasmic high.
It is a good idea to use something to catch the semen when you are masturbating. If you get it on the sheets, the couch or any other surface, it will leave a distinct stain- a stain that will be recognizable to your parents (including your mom - she knows what the stuff looks like, too!). The best idea is to use toilet tissue - you can simply flush it when you are done. If you use a t-shirt or other piece of clothing, and you don't do your own laundry.....well, you get the idea.
Males also experience a period right after they orgasm of major un-horniness. It is almost as if you're embarrassed to be in the position you're in. This is *normal* and is not something you should be concerned with. It is just the stoppage of the release of the chemicals in your body that make your orgasm feel so good. Once they stop, it is like coming down off a high from any other substance.
Autofellatio
Many guys (admit it, you're one of them) have often wondered what it would be like to perform oral sex on themselves. For some, it is possible. You have to be terribly limber and/or fairly well endowed, however, to make it worthwhile. IF you decide to try this, be careful that you don't injure your back. That would be embarrassing to have to explain, don't you think?
Eating Semen
It is not uncommon for guys to want to try eating their own semen. There's nothing wrong with it - I mean girls have been swallowing for years, so it obviously isn't harmful. And most guys just have a natural curiosity as to what it tastes like. Go ahead and try it. You need to know what you taste like anyway if you expect your girlfriend to swallow your load. If you have a partner, you may even wish to try experimenting with a technique called "snowballing." Snowballing is where you cum in your partner's mouth, and then your partner kisses you with your semen still in his/her mouth. You basically share your semen, or the "snowball." Again, nothing harmful about it, and it shows your partner that you don't mind tasting your own stuff - seems fair if you expect them to do it, right?
Can you masturbate too much?
Of course not. Unless it gets to the point where you are spending so much time masturbating that you are not getting your homework done, you have problems interacting socially, or some such, it really isn't possible to over do it. If you do it too often, however, you may find yourself with a sore penis, chapped skin, or whatnot. You don't have to worry, though, you won't run out of sperm! There's no such thing as an "addiction" to masturbation, though.
Masturbation as a prelude to sex
For some guys, especially those new to sexual activity, it is not uncommon to orgasm before you even begin to get really serious with your partner. This can be upsetting for the both of you. One suggestion that has always worked is to masturbate about a half hour or so before you start your sex session. This will allow you time to recover and be able to achieve erection again. Guys have what is called a "refractory period" once they've orgasmed - a period in which erection is generally not achievable again until your body recovers. Masturbating before sex will cause you to require a bit more effort to have another orgasm that soon afterward, and thus is a good way to remedy the problem.
