I'm just a girl with a friend that's a survivor, but you're post has been up for 45 minutes, and I think I should answer since everyone else is outside!
From what the guys write here, not responding doesn't mean anything other than -- You didn't know what else to do! When you're a kid, and you don't have any experience in life, and someone wants to do something, and you don't know what to say, you stay quiet!
As for not telling anyone, my friend, the reason I'm here, he was abused at age 5 and I was the FIRST person he told - - -when he was 40!
You're pretty typical.
You're not paranoid, you just don't know what to think. When the guys show up, they'll tell you your reactions were perfectly normal for a perfectly normal heterosexual child!
