Ok, now this is a topic I've done a lot of "research" on
Let's get down to business...
You may or may not already know that the all-powerful clitoris is the key... but just knowing what it is and touching it don't get the job done.
For anyone reading this that may not know, the clitoris is a small round thing (kind of, more oval than round) that is at the very top of the pussy on the outside. It hides just underneath the area where the two outer-lips meet at the top (up where hair would be if they didn't shave), and it "peeps out" a little and grows slightly when stimulated... just like our dicks grow but not so dramatically, on women it is barely noticeable.
The clitoris (or clit) is what gives women the most pleasure and the most pain during sex... that's why the most important thing to remember when dealing the clit is balance. Too much stimulation will make her clit so sensitive that she will become uncomfortable, while too little stimulation will never make her orgasm. Rubbing too hard on the clit will hurt her (remember it's probably the most sensitive/fragile part of her body... think about someone rubbing really hard on your sack, not fun huh?), but rubbing too soft will not stimulate her enough. So remember, balance is the key ingredient.
Rubbing on her clit in a circular motion before sex is highly advised, because if you do not do it then making her orgasm during sex will be much harder (some girls prefer clockwise, some prefer counter-clockwise... try both and whichever gets the best reaction out of her is what you should continue with). Do that for about 3-5 minutes while kissing her lips, neck and tits (get used to multi-tasking... it's a needed trait if you wanna be great in the sack).
Next tell her to start suckin' you off, you can skip this if you want to hop right in the puss... but personally I prefer the "best of both worlds approach". If possible do this with you lying or sitting on the bed in a way that allows her to be beside you so you can reach around her ass from behind and continue stimulating the clit. Around this point I usually start talking dirty and make them try to answer me with my dick in their mouth, talking dirty really turns them on and when they make noise while blowing you the vibrations from their vocal chords feels good and adds a little spice to the act.
After about another 3-5 minutes start hittin that ass. Don't be afraid to try a bunch of different positions, because this is important in making her orgasm which you'll learn in a moment. Spend at least 5 minutes in a each position as switching too often can kill the mood. Ready to learn something that'll turn you into a better lover than 99% of the guys in the world? Forget EVERYTHING that you've learned from watching porno! Porn stars are the absolute worst when it comes to banging girls, and the way that they do it in porn could not make a woman cum if they hit it for 10 hours straight. Let me explain...
Sex in porn movies is all about getting the "right angle" so the viewers can see all of the action... sex in real life is not supposed to be that way, well at least if you wanna make women orgasm it's not. You need to keep your body much closer to the girl's to make her reach an orgasm, so close that if someone were watching they would not be really able to see much of anything going on "down below". This is why porn stars are doing it all wrong, they bang chicks in a way that allows for good camera angles, not good sex... if they were to do it the right way then the porno would be stupid and the viewers would not be able to see anything.
So why all this close contact? It's all about the clit remember!
You could easily bang girls like the porn stars do and reach your hand down and rub the clit right? Sure you could, and sometimes that works very well... but if you really wanna "knock that pussy out" every single time there is a much easier and more effective way to do it... and thats by keeping your body close. The trick behind this is to gently rub the area that is just above your manhood but just below your stomach against her clit as you pump inwards... and when I say gently I mean very gently. Once you start doing this to her you will know immediately why it's so much better than using your hand, she will instantly start breathing heavier and moaning louder... she may even throw in a few "Oh shit"s or "Oh my god"s. This technique is pure gold.
Have you ever been watching a porno an noticed the girl start rubbing her clit herself while she was getting hammered? It was because she was lacking this type of stimulation... and that alone should show you how important it is. Girls CAN NOT get off without any clit stimulation at all.
While switching up positions you may flip her and start going at it doggy style (a personal favorite of mine), but then you'll instantly notice that you can't rub your body against her from this position. No problem... I have a quick fix : You need to substitute your hand in this situation because it is your only alternative... so reach your hand around her and do your thing while you watch that ass jiggle... problem solved.
Ok, by now you should have had enough fun and should have her hot and sweaty enough to be ready for the big moment... time to hit her with your secret weapon and make sure she'll NEVER forget you...
Have you been wondering why I haven't mentioned the G Spot until now? That is because the whole point is to avoid it until the last position you'll be in, this is where everything comes "crashing down" on her and she gets lost in a sweaty mess of ecstasy that'll leave her legs shaking for an hour. For those of you who don't know the G Spot is inside of the pussy on the top wall, it's kind of "behind" the clit... but don't worry about finding it... you don't have to.
Here is what you do : Lay her on her back and get on top of her and start hittin' it in the normal missionary position. Next lift both of her legs up REAL high and put the back of her ankles on your shoulders... then make sure to put your arms on the inside between her legs and you. This allows you to kinda "hold her in position" while you pound away... women love the feeling of being dominated during sex and this helps bring them to an orgasm. Next pump once or twice (remember close contact, you should be rubbing all up on the clit right now... a little harder than before) and when you do watch her reaction. She looked at you like "Holy ^%$#, your the man!" didn't she? You know why? It's because you just came with everything that gives her pleasure in one powerful pussy pounding package all at once : You are holding her down, your dick is crazy hard right now (because this is the best feeling position for us as well), your are rubbing her clit with your body, AND... you guessed it... now your hitting her G Spot. Don't worry if you don't feel it, from this position it is impossible to miss the G Spot at long as your dick is over 3 inches when hard... because thats about how far in it is on most girls. Sometimes you can feel it with every pump, but other times you don't feel it at all... I have no idea why but it really don't matter because the end result is the same.
Only one thing left to do... Start nailin' it!
She will orgasm from only about 2 minutes of this, 5 max. Just control yourself because this is where your mind power will play a major role... you need to make sure not to blow your load before she cums! This is going to be harder than you think because when I say this position will feel good to you I ain't playin'... it feels REALLY damn good, and it'll make you ruin all of the work you've done if you let it. Just keep your mind clear of any thoughts about sex and keep doing your thing... also try to ignore what she does because at this point she will be screaming and moaning like crazy and may be scratching the hell out of your back... all of which are things that can distract you. Keep at it till she gets hers than get yours in as well... light up a smoke and listen to her tell you how much better you are than anyone she has been with and how she never thought sex could be that good.
Only thing you gotta worry about now is how to make her leave you alone
*NOTE* The guide you've just read contains all of the physical techniques required to make a woman orgasm... but that is not the only stuff you need to know how to do if you want to be the perfect lover : Talking dirty, playing upon her fantasies, creating the right SPAM and mood, role-playing, Etc... are all examples of things that can amplify the effects of the physical stuff you now know, and all deserve an article themselves... keep an eye out of those in the future!

One of my favorite techniques is to lick out letters/words/phrases on her crotch, using big slow letters. I'll spell out "SWEET PUSSY", or "EAT YOU", or "I LOVE YOU" (if it's my wife), or something similar. Even if they don't know you're licking letters, the variety and perceived randomness still feels awesome I'm told. This is a really good warm-up and it takes a while, which is good.
