Dr. Robert did write something about memories "recovered" by means of hypnosis in a post called Is there a way to recover blocked memories.

He also discussed in another article how momories of sexual abuse can be put into the therapy room by the therapist or the hypnotist.

He seems to believe that there is a danger that therapists can find memories of things which never happened.

It is true that people can create memories just by having someone suggest to them something happened. I wouldn't suggest trying to dig up old memories, it could simply make matters worse for you.
From what you describe with the mistrust with men, the memory with your uncle, your cousins and unable to relate sex with love it seems likely something may of happened. I'm not saying anything did and most people would say not to think like that but it does seem likely. Do not worry about that though, you don't know for sure and you can't change the past, the issue now is the result; not relating sex with love and mistrusting men!
As I said, digging up old memories will probably make matters worse, but seeing someone to help you associate sex with love and to regain your trust in men will surely help your whole life, which may mean bringing back suppressed memories for that purpose, if there are any.
Simply remembering if anything happened won't help, understanding why they happened and learning to re-trust men will.
I hope I've helped.
