I had a similar situation when i was 6 with my older step brother who was 13 at the time...it was all just a game of "truth or dare" so i didnt know any better. i didnt realize that he had taken advantage of me sexually until i was 14 and still today i am only able to remember a few visions and very minor details but i cannot remember everything. i too have a "memory block" and i am not sure when i will be able to overcome it. i am not an expert on this so please dont quote me...i am just sharing a similar experience and i hope my story has helped you.
good luck and god bless
