I was sexually abused when I was 6 to 9 years old by an older boy (12 or 13 years old?) who was the son of my parents’ best friends. I have only recently been dealing with all the issues including recalling memories and the details. It is my understanding that the boy who abused me is dead (supposedly committed suicide about 10 years ago).
My parents are the only people left who have any knowledge about the abuser and the times surrounding my abuse.
What an interesting name, and your inquiry is interesting to me. In fact, I could use exactly the same words to describe abuse I experienced at the same ages. However, I experienced abuse from other perps additionally in other ages.
In addressing your question, I am wondering how old you are now, and how old are your parents. Did you go through a time of repressing the memory of the abuse, as most of us did? Did the abuse go on and on like daily over those years, or was it a few times a year? All of these things would influence the course of action you should take. I'm sorry, I'm not trying to be difficult but I'm just trying to point out all of the factors in your decision. Do you have anybody to talk it over with in person, like a counselor?
I can understand why it would seem vital to talk to your parents about this, since they knew the family and might remember the boy abuser from an adult perspective. You also sense that it would be difficult for them or else you wouldn't be asking the question as you did.
Most of the guys I know about here find it very difficult to share with parents. It is often one of the last steps in recovery. It can be quite shocking to them and it requires a complete adjustment of their memory of you and who they assumed you were. They may feel very guilty, as someone already mentioned. Sometimes parents can even be angry or rejecting, depending on who they are and what their mental construct is. I of course don't know them and what their attitudes might be. I would need to know more about them and about you.
If you do decide to share with your parents, you need to have a well devised strategy, including thinking about even the words you would use and how you might answer their questions.
If one of your main goals is to obtain information about your abuser, you have some options like checking school records. If he abused others, there might be some court records. There might even be some old newspaper articles in the archives of the local newspaper where you lived at the time. I've had tremendous curiosity about my abusers and information has been hard to get.
I hope this has helped a little bit. Feel free to ask additional questions if you wish.
