my girl firend has an intersting problem.... she has a verry verry hard time obtaining orgasm. ie she gets to the verry edge of orgasm and just stays there, tilll she's twitching and shaking with her eyes rolled into the back of the head like shes having a seziure.....she usually winds up pushing me away before she gets off, and is so exhusted she passes out near instantly . any ways...any sugstions for getting her over that edge. she never complains but i know she is frustrated.
