Here for my own selfish reasons, but while I'm waiting, I'll give my two cents. Has she orgasmed regularly with all her other partners? How many has she had/ did they come from sex? Honestly, a large part of problems comes from the emotional/mental part, not the physical one. I've had sex with a few women who didn't orgasm, they got all embarrassed, and I just told them to relax and enjoy what we were doing. They started orgasming rather soon after that. Likewise, an ex who I hooked up with again for a while went from the multi-orgasmic female I remember to... not (and no, my technique and staying power are the same

). Don't push it. Let it be. If she's going to orgasm with you, the best way is to make her feel comfortable and relaxed, and to let her enjoy herself.
