The men may not be as interested in this, but the women may find it interesting, because it's one of the common ways a man will masturbate.
I still like to use just my hands, mostly my left hand. I like to watch myself while I do it too. Even in the car on long drives I can masturbate for an hour or two, off and on, glancing down at my erect cock occasionally.
I start out 'dry', just barely touching the skin with a ring of thumb and finger. After several seconds I switch to a gentle pulsating squeeze at the base of my penis. That keeps the stimulation going but doesn't force the orgasm-yet. I can keep this up for a very long time, gradually increasing the sexual tension each time I slow down or stop for a few minutes.
As I get close to cumming I let the ring of thumb and finger get closer to the most sensitive part of my straining cock, just behind the flare of the head. Movement is very rapid now. Then I switch to a full-hand sliding motion up and down the shaft. The erection is now almost purple in color, the skin stretched, my cock about 6 1/2 inches long (I've measured it as long as 7 inches, along the top, from base to tip). The opening of the cock is spread, oozing thick clear fluid. Sometimes there will be little spurts of that fluid. But I try to keep stroking on 'dry' skin. I know that's unusual, but that's what I do.
When I get so the cum is inevitable, so I couldn't prevent ejaculation no matter what I did, my pelvis will be flexing forward a little, involuntarily. There will be little spasms deep inside somewhere. My hand is moving as rapidly as I can move it, absolute maximum stimulation.
Then I come-come-come!! Usually the first spurt is the longest, thick whitish fluid. It will go out a foot or more, I think sometimes almost 18 inches though I've never been able to measure it at that point. With the best orgasms, the best cums, there will be four or five spurts shooting out. The last ones are thinner and less whitish. Then there are shorter, smaller, flows of grayish fluid.
Of course, I also do it in the shower sometimes, using soap, so I don't always use the dry technique.
