Ok, hereare somemore ideas I wuld like to add to the above mentioned ones:
First of all relax! Make an atmosphere where she will feel cosy, confortable, romantic.
Really maybe talk to her, ask her what makes her confortable. Maybe she wants the lights on or of, maybe she would prefer keeping her clothes on, maybe she would like to do it in the kitchen...and if she happens not to know, then be open to try out it together with her. be creative, explore together what is good for her. Some women do not know what they want, like and need help with that.
The make her feel sexy, beautiful and wanted not just when u make love. Show your love, show that you care for her, your feelings for her. Hug her, be gentle to her, do the dishes of things insteda of her , or something like that. tell her when you like what she is wearing. Compliment her. It will make her feel more confortable and trise her self asteem. Many women cant orgasm because they do not feel confortable with something. Communicate with her and find out not what is wrong, but what makes her feel good, what she likes.
And important one! Sex is not about reachingthe goal! Orgasm happens, but it is not the goal. Put focus on intimacy, being together, having FUN together, enjoying each other presence. I myself cant orgasm when so much pressure is put on getting it there! IN situations like this aman can be doing all the right thingsfor hours if he wants and will never get me there. women orgasm starts in her head- in her thought, in the way how she feels , in the intimacy she enjoys LONG, I mean here very very long foreplay can help...and dont quit working on her. Some women need lots of time, and that is how they are. It is rather frustrating when your boyfreind stops it, because he is tired and u have almost got there!
Also read all you can about what women like in general, what techniques and maybe toys you could use. I thiknthe more u know about women sexuality, the easier you will know how to get her there.
And the most important: communicate, communicate, communicate. Pay attention to her while you make love, maybe even ask her. Talk to her before, during and after.
I wish you good luck, and I hope all this helps
