Hmmmm. Dunno if this is necessarily the right place for this. You might find more support in other forums... But since you asked.
"What do You think of my sexual development?"- Uhhh not touching that one.
"Is the attraction to children by itself wrong?" I don't personally believe we can control who we're attracted to. Since it's not a choice, I don't think morality comes into play. That answers the next question too I guess.
"Is fantasizing about children wrong?" Eh I guess I don't think so. It seems to fall into the same category as attraction. But, there is perhaps a gray area if it's a child you know, or spend time with. That might be problematic if it encourages action.
"Is age play wrong?" I don't think so. What two people do in the privacy of their own bedroom is really nobody's concern but their own.
