Hello, don't feel bad or you did something wrong. My daughter was 6 years old when she started talking about sex. She heard about it from my friends son and told me details that made my mouth drop. So I was honest with her and we started talking about it. Now I didn't give to many details at first but as she grew we kept talking about it and then I gave more details. I felt that being honest was better then making it sound bad or not talking about it at all and having her want to go and do something when she got older. I hope this helped?
