Hello. It is indeed common for people, ( men and women ) who have been molested or sexually abused as children to later experience a variety of sxual difficulties. And this can obviously cause problems within a marriage. Skilled counselling, such as the Cognitive-Behaviour Therapy form, can greatly help such a person to get themselves free from the aftereffects of what was done to them, and set them free to enjoy sex freelly, and thus to more readily enjoy close relationships such as marriage. Is your ex wife open to the idea of seeking and working with a good local therapist ? I so, it sounds from your message as though you would be interested in encouraging her to do so, and perhaps reconsidering the marriage / relationships ? If you both share that idea, maybe some couples counselling after she has worked with her individual counsellor, might be worth exploring
