I'm not sure exactly how old I was when I first started masturbating -- either 11 or 12 -- but I know I was curious about my body, other people's bodies, and sexuality from a very young age. At age 7 I remember lying in bed, pulling down my pants, and holding up my erection to look at it. There was no stroking, no sexual feelings at all -- just curiosity and amazement. At the same age, I became fascinated with the female body, having seen some female nudity in movies with the help of my older brother, and wanted to know what they had in their pants.
This technique is similar to the Milker. Instead of beginning at the base of the penis and going up toward the head, use both hands and do this in reverse. It is important that the penis and both hands are well lubricated. Make a "C" with both of your hands, and then stroke your penis downward. Rest the bottom of your palm at the tip of your penis and bring it down; when the bottom of your palm hits your body, do the same with your other hand, bringing the first to the top of your penis, and repeat what you did before.
This technique is perfect for guys who like a lot of scrotum stimulation. Grab your penis around the base using the regular "fist" method, but make the Hawaiian "hang loose" sign, with your thumb extended toward your penis head and your pinkie extended toward your testicles. As you masturbate, your thumb directly stimulates your penis head and your pinkie jiggles your scrotum. You can do this lubed or dry, but you might want to lube at least your head/thumb. This can be done lying down or standing up. It will have you saying, "Alohahhhhhhh!"
A semi-hands-free technique: Simply clasp your hands together by interlocking your fingers tightly; then lower your arms and get your penis to rest in the V between your forearms. Masturbate normally, by moving your arms together. The effect is better if you resist letting your dominant hand control the movement – let both arms move as one. The freedom of not having your penis clasped seems to encourage a good ejaculation. You pretty much have to be standing to use this method, but it's more interesting than the "fist," but it can still be done in a tight space like a shower.
Masturbate normally with one hand, with a bowl or pot of ice water nearby. When you feel yourself start to get close to orgasm, put your other hand in the cold water. When you are about to ejaculate, put your now-freezing hand onto your testicles. It might give you the biggest orgasm ever!
Sit, recline, or lie so your penis points straight up in the air. Grip it relatively low, near the base, and make fairly short, fast strokes. If you stroke with a slightly circular motion, you'll find that your penis head "whips" back and forth. The idea is to find the exact stroking rate that matches the sympathetic resonant frequency of your penis – guys with shorter penises will have to go faster to get the proper action. You'll know you are at the right stroking rate when the head whips back and forth with a motion opposite that of your hand.
With one hand, do the typical "up and down" motion – but with one finger of the other hand, circle around the head of your penis. This resulting orgasm will be great!
Lie down on your side and hold onto your penis with the Backhand grip. Roll over further and brace your hand against the bed, and thrust your penis in and out of your hand. This closely mimics the movements of intercourse. It's a very different feeling to masturbate by moving your pelvis rather than your hand. It's also fun to put your other hand down and feel your scrotum moving back and forth as you pump in and out of the "vagina."
