Hello and thank you for your question:
I wish I could answer your question, but there are so many other questions that I would need to ask you to give you a fair reply.
The problem with suppressed memories is that often they aren’t real. We honestly have trouble recalling things from the time that we were 4 (or, in your case 6). There was a lot of press that came out many years ago about suppressed memories and often these memories were proven to be untrue.
However, that is not to say that what your sister remembers is false. I’m not saying that. What I would suggest is that you ask yourself this: Do you have trouble in relationships now? Are you sexually active and do you think you have problems with sex? How do you view men?
If you can say that you do have problems regarding intimacy or trust, you might want to seek help. Little kids sleeping with adults isn’t rare or unusual, and if you don’t remember being in the tub with the man, that may have been harmless or may not have occurred.
I am not dismissing your question, quite the opposite. If you feel you have been molested, please talk with a professional (not just a friend or colleague) but a therapist you would see on a professional basis and investigate this.
I hope this helps,
Dr. Diana Walcutt
