I think the research literature/statistics has been misrepresented, but commonly repeated.

1. In the population of people who have been sexually abused as children, the vast majority of victims do not go on to become offenders.

2. In the population of perpetrators, some to many have been victims of sexual abuse. Being victimized and then perpetrating on others is more common in juvenile offenders than in adult offenders.

1 and 2 are very different things. It depends what group of people (victims or perpetrators you start with). But you have to know both statistics to really understand the relationship between being abused and then perpetrating on others.

This information is an easy Google for anyone who wants to look into it. Here is one website with specific statistics: Statistics on Perpetrators of CSA.

One thing to remember is that the statistics might be not so accurate because we don't have any way to know the complete population of abusers. Those who are caught by the child welfare or criminal justice system may not be reflective of the entire population. We just don't know a lot, which is why I would be thoughtful about any statistics and blanket statements from others when thinking about what kind of therapy might be appropriate for you.

I'm a CSA survivor and I have the unfortunate ability to know that for sure because of physical damage to my body that is irrefutable. I have always had some memories and entered therapy when the circumstances of my life were difficult because of jacked up PTSD symptoms. I am glad that my therapist (and two subsequent ones) never went "looking" for memories but they appeared at various times and I have continued to process them in therapy for many years.

For me, being able to articulate what I went through and having the memories become more flushed out over time was just very, very crucial to my healing. I can very much understand wanting to have a memory that belongs to you and wanting to know what happened. Our memories do belong to us and it has been true for me that having them return in a meaningful form to me felt like I"d gotten back a part of myself.

I am a worried about a therapist that wants to go looking for memories. I do not see a therapist's statement that certain behaviors/feelings/beliefs are consistent with CSA as troubling. I think for a therapist to be silent in the face of what they think signals CSA (and for the sake of argument am just assuming they are correct about it) is not helpful at all to a client.

In law, questions themselves are not leading or "planting a seed." Planting a seed may also just refer to normalizing something that a person may have difficulty coming to understand themselves without any help. Suggesting a possibility does not mean forcing the person to accept it or pushing one answer over another. A position like "let's explore this further if you want to" which may or may not be how your T is approaching it, seems sensible to me.
Burying one's head in the sand and refusing to consider it does not.

Asking a question "have you been abused" or stating it as a possibility allows the person on the other side to say what is true for them.

A way to move forward, assuming you don't want to end therapy or switch therapists, might be to opening discuss your discomfort with your T. Ask her the questions you asked here, see what she says. Ask her about the basis for her belief, and whether other possibilities exist. Have her explain why she thinks moving forward in this technique will help you. Ask her what will happen if memories emerge, and if they don't. Ask how you will benefit from her approach, and whether other ways of moving forward might be more effective. It seems to me that you are at a crossroads here, and it makes sense you want to stop and more fully consider what to do. I wish you the best with it.
