Have you been raped? No? Would you then kindly not make assumptions how long it takes to finally get the courage to admit to it?
Many people suppress traumatic experiences. It's rarely successful, but it sometimes works as a coping strategy. For a while. All it takes is one triggering event to bring it to the foreground again. If that event happens ten years later, that's when it happens.
Yes, it's a long time. Unfortunately, that's the way our brain works, sometimes. The OP seems to understand that.
