Alright, since they don't, let me tell the true story.

1. This isn't a "kid". He was 17 when he made the request, he's 18 now.
2. It probably wasn't Make a Wish, not sure on that one
3. There's barely been any porn of the character because these are facts we know
4. None of the creators ever said not to make porn of the character
5. The only one who objected was his mom, who stopped because she realized she was being overzealous and her son accepts art of all forms.
