for starters your therapist should not be trying to force his opinion of the situation on you. If you ask him first if something sounds like sexual abuse or you have already reached the conclusion that you were sexually abused then he can agree with you or he can say whether or not he thinks it could be but the two of you would have to wait to see what develops first to be sure. He is not supposed to come to the conclusion then make you come around to his conclusion. As to whether or not all this means you were sexually abused only time will tell as you gain more memories about your childhood. It could very well have been that he had just tickled you like your sister said or he tickled you in a way that made you uncomfortable or he could have sexually abused you but I can't tell you which it was because I was not there. the truth of if you were sexually abused is somewhere locked in your brain and unfortunately it may take time before you know that answer for yourself. People remember things at their own pace not on a textbook type schedule. And no you wouldn't necessesarily remember in fact most survivors do have memory lose of some kind related to their abuse. It could be just one situation of many they don't remember or it could be a whole string of situations they have forgotten because the situation was more tramatic then they could handle. and when survivors start remembering what they lost it is in the form of nightmares and flashbacks, not by the therapist telling the client they think the client was abused. In fact there is now a problem called false momory syndome in which therapists have been known to force clients to believe they were sexually abused when they haven't. If your situation was mine the next time the therapist brought up sexual abuse with out you initiating the topic I would say if I was sexually abused I was sexually abused if I wasn't I wasn't but at this point I don't have enough memories to go in either direction so I am remaining neutral. Then go on with a topic in my life at the present that needs to be taken care off now. What ifs will take care of themselves in time. I do know that in order to work on sexual abuse related issues the person is better off having a strong network of coping skills and support systems and so on in place because once flashbacks and nightmares of this kind hit a person they need all their strength and resourses to keep afloat and paddle to shore at the same time. Hang in there and go on YOUR gut instict not your therapist pointing you in that direction and forcing you to beleive you were abused.
