Advice from a women:
Let me just tell you all it DOES matter whether we orgasm or not and as a man you should feel ashamed not to make this happen. She cares whether you come properly and more than likely will not give up until you do! It also matters what type of orgasm she has. She wants it to be better with you than it is on her own obviously which means it should be slower and stronger!
This does not apply to one night stands. Those girls have low self-esteem and probably don't care about themselves enough to really demand an orgasm but I am going to give you advice when it comes to a real women..
First of all you should focus on her ****oris. use your hand to stimulate her gently. Do not touch the **** directly as it is too sensitive (it looks like a bean-look it up if you do not know where it is), touch around it consistently until she orgasms. Our **** is actually quite similar to the male penis and we even have skin around it like a hood which is similar to foreskin so use your imagination.
If she has an orgasm, her vagina and cervix will contract 3-10times and her ****oris will move a little. This happens to all women and she cannot control it. She also will not be able to talk during orgasm (she may just be able to manage your name or 'oh god' or 'yes' or something similar and some girls moan softly, others don't at all. Be wary of any girl who screams during a ****oral orgasm. She is probably faking.. If she says anything else she is not having an orgasm! And it should be a lot different to what porn women do lol. Her nipples should be hard and there should be a little puddle underneath her. She will arch her back and her hips and may even move her body towards your hand. If you do give her an orgasm she will want to lie still for a few moments and will then want to cuddle and talk or cuddle and fall asleep. That is if she has already made you come, if not-she will do that..
Once you have mastered that, the next step is your tongue which is the same as using your hand-just better.
And then finally using your penis! The best thing to do here is have her nearly there with oral before you enter her to guarantee an orgasm and make sure you move up and down on her ****..
If you are unsure just ask and if you do not want to ask keep going until she asks you to stop. Our ****oris gets very sensitive after we come so we WILL tell you to stop if we have already came. It can also get sensitive though if you touch it directly so work the skin around it and move the skin on top of it etc (the same as you do when having a wank just more gently)
After that there is lots of other orgasms that you can try to give her but do not go from 0 to 100. You need to get the basics right first. Girls have lots of patience and we do not mind waiting for the big O but if we are left disappointed too many times we will just think you are a selfish pig and start to wonder about the other fish in the sea. Just saying!
It should make you happy to give her pleasure and you should love watching her come. If you dont there is something wrong with your brain.
