I definitely agree with the first comment. I've lived through a lot of trauma and it's made my memory pretty awful. Sometimes I'll randomly recall a fraction of a memory; smells, feelings, thoughts, visuals, and so on. It can be difficult to know what's a genuine memory and what isn't - but a professional like a therapist can help you sort out why you're suddenly recalling certain events, and help you overcome the shame that you have regarding how sexual you were as a child.
