Speaking from personal experience as well... it may take your gf a while (with therapy) before she will be able to allow her body to enjoy the sexual experience as it was meant to be - please be patient and keep doing what you are and dont put so much importance on her having to obtain an orgasm to enjoy being with you sexually.

P.S.
Have her look into getting this book (dealing with old wounds)
