This will probably sound like the worst thing a person could say, but...don't do it.
What I mean is that life in the present is hard enough with out digging through possiblitites of the past. I sincerely mean this with the utmost of respect for you and personal knowledge of issues you are concerned with. Those who did have an experience and share it's memory try to do everything they can to move forward and past it. If I could erase the memory and the lingering issues it has made me deal with growing up I would happily do so.
If something did happen take it as a blessing that your soul decided for you that it just wasn't something you needed to hold on to. Life is for the living of today...yesterday doesn't help you anymore.
