I know it's not quite the same as not sexual abuse... but untill very resently I had basically no memory before I was 12, and what I did have was in part reconstruction from what others had spoken of since...

I've started to build up an idea of what happened then now though, mainly bits appear in dreams, or a bit like flashbacks but disjointed flashbacks if that makes sence...

I'm not sure if there is a way that you can "force" such memories to appear... maybe ask your theripist about that? I've been told though that such memories usually do reapear at some point, suosidly once you're ready to deal with them.... though in my case that theory was a bit wronge I think :s

sorry, I was probably no use here... but I know what it's like to think something may have happened but have no recolection of it and to have little memory of your childhood, so you're not alone in either of these things...

good luck with recovering these memories however/if you decide to do it
