What do you mean by abusing younger children? You said you never did that as an adult. Kids touch each-other quite often. I did it with other kids as well, some were a bit older, others younger, and some my age. But all of them kids. Also had similar curiosity about animals, many times. So many people do - just think about all the porn created about it. Won't say about doing it but thinking it - why would it be wrong or abnormal?
