I'd been reading the "length or width" thread and a recurring theme seemed to be "how to use it". So how do you want it to be used? Besides just in out repeat (although that can be fun as well)
I'm sorry sweets, but if you don't know the answer to that question by now, I don't think I could explain it to you properly. I'm sure someone else could though.
Knowing how to use it simply means using it to the best of its ability. If you're a two-pump chump, make those two pumps count. If you can go all night, is the ride worthwhile? If you're somewhere in between, the same question applies.
You're right, it's more than just in and out. How vigorous are your thrusts? Are you switching between slow and fast? Are you changing positions? Is your chosen position the best for your cock length/width? Are you bringing her/him/yourself maximum pleasure?
These are the things you should keep in mind in terms of 'using it'. And I just mean your cock alone. No other implements or aids. Just you and your dick.
Happy humping!

That's not a matter any of us can advise you on specifically. Every partner is different. Everyone has different preferences. I think the best advice I can give is to vary your routine. Experiment. Consider other activities besides intercourse (vaginal, anal, oral), but also don't neglect it.
State secrets, man. I keep the moves under lock and key in a firebox. I have an evil care bear stare guarding that thing.
Seriously, different strokes for different folks bro. Your lady with let you know what's working...if not. Change it up or you're fucked.
Penis owner's instruction manual
STARTING THE ENGINE
The key to your sexual ignition is not between your legs, it's inside your head. The brain is man's biggest sex organ, sending nerve impulses running down the spinal cord to trigger an erection. Keep in mind though that since arousal is an electrical spark travelling the neural motorway it can be dulled by a repetitive commute. So vary your starting procedure, explore side roads, stop at a roadside service area, let your partner drive, or, when applicable, road-test a new model.
HARD STARTING OR STALLING
If your penis fails to become erect, even after repeated cranking, or if you have trouble maintaining an erection, let it idle for a while. Just about every man experiences an occasional erection problem, so try not to let it bother you. If you do it can develop into a psychological problem that can require extensive systems analysis to remedy. Chances are you are just temporarily flooded with work worries, anxiety or fatigue - all of which can temporarily foul your engine. If the problem continues, ask your mechanic about a new injector. Certain drugs can be injected directly into the penis, producing longer lasting (one hour or more) erections within moments. Coming onto the market is a plunger-type system that inserts a small pellet of erection producing medication into the tip of the penis. Another solution is a vacuum constriction device: when the penis is inserted into this cylinder and the attached pump engages, a vacuum is produced that causes blood to flow into the penile shaft. A rubber ring is then slipped onto the base of the penis to trap the blood in the shaft. As a last resort, you may want to consider upgrading to a penile implant. (See "Available options/upgrades").
CAUTION! The following can shrink a relaxed penis by two inches or more:-
Cold weather, chilly baths or showers, sexual activity, exhaustion, excitement (non sexual), illness and Richard Branson.
OPERATING INSTRUCTIONS
DIRECT THE FLOW OF URINE The penis contains a narrow hose called the urethra that is attached to the bladder. As the urine level approaches the bladder's maximum capacity line, you get the urge to pull over. When released, urine is flushed through the urethra, out the tip of the penis and, according to most women, usually on to the floor next to the toilet. Acting as a regulator for this process is the Pubococcygeal (PC) muscle. This is what you flex to stop urine flow or rid yourself of those last few drops. (It can also serve as an orgasm regulator. See Troubleshooting" later in this document.)
BECOME RIGID ENOUGH TO ALLOW PENETRATION DURING SEXUAL INTERCOURSE Your penis is equipped with twin hydraulic chambers. During sexual stimulation, these fill with blood until the penis grows firm and erect. After stimulation ends or there's ejaculation, blood leaves these chambers and the penis softens again. There is usually a recovery or "refractory" period ranging from a few minutes to a full day (depending on the equipment's age) before another erection can occur. About half of the penis is hidden inside the body, even when erect. It is fastened to the pelvis undercarriage for support.
DEPOSIT SEMEN WITHIN THE VAGINA DURING EJACULATION Sperm is manufactured inside the testicles, those two ball joints below the drive shaft. From here, it passes into a soft, fibrous organ behind each testicle called the epididymis, where it acquires the long tail necessary for swimming. Sperm then enters the Vas Deferens for storage. This thin hose loops around and splices into the urethra just below the bladder. When it's time to shift into sexual high gear, sperm is mixed with liquid from the prostate gland and adjoining seminal vesicles. The resulting transmission fluid, called semen, gathers in a holding tank, which gradually swells to pinch the bladder shut and prevent urine from trickling in. Finally the semen is expelled from the body via the urethra by a series of muscular contractions.
CAUTION!
The testicles need to be slightly cooler than normal body temperature for optimum sperm production. That's why they hang away from the body. Hot baths and tight underwear can depress sperm count and movement.
WARNING!
Never operate your penis while under the influence of alcohol. Although alcohol lowers inhibitions, most men have less than optimum erections when inebriated. The fear this generates can lead to more frequent bouts of impotence.
SPARE TYRE
Your privates did not come equipped with a spare tyre. Any roll of fat around your middle was an after-market acquisition that will void the warranty if left in place. It not only interferes with sexual performance but also makes the penis look smaller. Men naturally deposit fat in their abdomen, which includes the area at the base of the penis. As the spare tyre inflates, this pad thickens and eventually engulfs a portion of the organ - one inch for every 35 extra pounds. Being overweight is also commonly linked atherosclerosis, or narrowing of the arteries, a primary cause of impotence. It also makes you look silly.
RUNNING-IN PERIOD
To ensure a long, active life for your privates. It's recommended that you engage in frequent sex. According to noted body mechanics Masters and Johnson, "When the male is stimulated to high sexual output during his formative years and a similar tenor of activity is established for the 31 to 40 year age range, his latter years are usually marked by maintained sexuality.
ACCELERATION 0-60 MPH
Independent testing shows that it generally takes three to five minutes for the flaccid penis of a young male to become fully erect once sexual stimulation begins. This reaction at least doubles with age.
WARNING!
Avoid rapid acceleration on slick surfaces. Failing to do so could cause partial or complete loss of control.
MAINTENANCE SCHEDULE
Your privates are the result of centuries of engineering. Before leaving the factory, every effort was made to ensure that they were in good working condition. To keep them running smoothly regular maintenance is required.
TO BE DONE DAILY
It's especially important for uncircumcised men to retract the foreskin and wash around the head of the penis every day.
TO BE DONE WEEKLY (AT LEAST)
Sex is the best exercise for your privates. Regularly flushing the system with nourishing blood and oxygen assures optimum sperm production, prostate health and overall good performance. When intercourse is not possible, consider revving your engine manually.
TO BE CHECKED MONTHLY
After taking a warm bath or shower to relax the scrotum, you should gently roll each testicle between your fingers. It should be smooth and oval shaped, feeling kind of like a hard-boiled egg with out the shell. Compress it gently, searching for any hard areas or lumps that don't feel like the surrounding tissue.
YEARLY INSPECTION
Once your equipment reaches forty years old, have your prostate checked annually. This gland surrounds the urethra like a doughnut and, if left to enlarge, can reduce an older man's urine stream to a dribble. Prostate cancer is also a concern. Both of these problems can be avoided if detected early. A complete yearly inspection should include three things: A digital rectal exam (sorry mate but we're talking finger here, not computer). A blood test for prostate-specific antigens (psa), an early warning sign of trouble. An ultrasound scan to create a visible image of the tissue.
WARNING!
Using your privates for anything other than their intended purpose voids all warranties, written or implied.
SERVICING
The frequency of ejaculation/Intercourse among:-
20-29 year olds = 4-5 times weekly
30-39 year olds = 2-4 times weekly
40-49 year olds = 1-2 times weekly
50-59 year olds = 0-1 times weekly
60 plus = 1-2 times monthly
Shagnasty = 5 times daily! (Oh Yes my friends)
FLUID LEAKS
After urinating, apply gentle upward pressure under the base of the penis. This will usually squeeze out any remaining drops and prevent any embarrassing stains on the upholstery.
LUBRICATION ADDING OIL
For extra comfort and performance during long drives or when operating your penis in extremely dry conditions, you'll need to relube. Brands such as K-Y Jelly can be reactivated with a simple spritz of water.
DISPOSING OF USED OIL
When indiscriminately discarded, used oil can foul the bedroom environment. Flavoured lubes leave a sticky residue the required a soap-and-water scrubbing. Most no flavoured brands wipe clean with a towel.
TROUBLESHOOTING
The diagnoses outlined are intended to serve only as guides to locate and temporarily correct minor faults or worries. Causes of unsatisfactory performance should be investigated and corrected by your doctor.
I'm really surprised I expected to hear about things like clitoral alignment and long strokes or short strokes, rubbing the head on your g spot on the in stroke or out stroke. Maybe I'm on the forward side of the curve? Oh yes and you can write your name in the snow too!
*delete double post - though I do like hearing myself talk*
Maybe the question should have been "How do you like it used on you?"
Then the answers may have shown some commonalities to draw from.
Think of it, as an internal massage and a drilling rig. 
who knows? if you do it properly, you just may hit a gusher.
