I just want to say one thing.

"I guess I just can't comprehend what would be attractive about that."

I've come across people who have said the exact thing as that. I simply try to explain that in the same way you would be attracted to a man, a pedophile would have those same feelings. I don't know why I am attracted to any boy, but I am. The attraction is just there. But it is totally understandable why you can't comprehend it, for you haven't experienced it.
