I'm searching for all the help i can... 
I've been dating this girl for a few months now and no matter what i do, she does NOT orgasm. Sometimes she doesn't even enjoy it. We're both really open about it and she let me know I'm not the first guy this has happened with. At first i though i was doing something wrong, but my past girlfriends have assured me that their orgasms were many and that my style had worked in the past. WHAT CAN I DO? How can i get my "not-very-sensitive" girlfriend to have a good time? She DOES get aroused (ie. Wet), but after that it just goes no where. Any techs or tips are much appriciated.
Thanks everyone.

Well, when you are having oral sex, or anything else with her, take notice of the way she's reacting to what you are doing. If you notice she's beginning to breath harder, or if she tells you that she's enjoying it, or any other way that she lets you know she likes what you are doing. You have to pay attention to these signals. Maybe in the past there was something you did that she really liked but you didn't notice that she liked it. Try many things and see what gets the best reaction out of her. Then you know what to do.
If that doesn't work, ask her what she likes, ie. her favorite sex positions, maybe she likes to do kinky stuff etc.
Also, can she orgasm when she masturbates? If so, ask her to masturbate infront of you so you can learn what/how she does it to reach an orgasm.
Hope that helps.
Her problem may be a medical one. Here's a quote from Women's Health:
"According to the findings of a NIH-sponsored survey published in the Journal of the American Medical Association (Feb. 10, 1999) 43 percent of women report recognizable sexual dysfunction. Problems range from not being able to have orgasms to having no sexual desire at all."
For more info on it do a google search for women's orgasm problems, there's a lot of info.
