I could not say anything to you that would be more insightful than what Ken wrote to you.
I think that many survivors of CSA think about kids at the ages they were when they were assaulted. Sometimes we become very protective of them, and sometimes we may think about them wondering if they have been abused.
Do you think that you might think about guys in a sexual manner as a way of trying to understand what it was in you that lead an adult to abuse you? Wondering if the kid you see would react the same way you have etc.
As Ken says, if this continues and makes you really afraid that you could possible step over the line, then it is time to see someone who knows a lot about sexual abuse issues.
But, don't create a crisis if there isn't one there. We usually have enough crises as it is.
If we do not live what we believe, then we will begin to believe what we live.
