Good, well-trained and experienced psychologists and those who work with hypnosis don't drag things out of any patient, nor do they lead them to say things. Usually sudden exposure to memories that might contain abuse is not a good thing.

You might try couples therapy, or even sex therapy as your focus (together) just be sure the therapist can handle abuse issues, should they arise.

Yes, it is possible you "just" don't remember without anything being in your past, but that would probably require some type of neurological problem, I think, such as from head trauma.
