I had a gf exactly like this recently. And other girlfriends in the past much like this. It could be many many years before she is ready for sex. I bet she has some emotional problems, probably stemming from bad experiences with her ex. Just because she had lots of sex with her ex, does not mean it went well from her perspective. She could be traumatized from her past experiences. She may never want sex ever again.
I think you will also find that her trauma and emotional scarring will present significant problems to your relationship. Such as her over reacting to things. Just wait and see how things go.
My experience with these girls is most don't seek help and they never change. Why waste years of your life when you could be happier with someone else who actually has sex?
I have a long time interest in psychology, specializing in relationship dynamics for 30 years.
