Well my point is as far as all the accusations go "he had little boys in bed with him at his Neverland ranch" is usually the primary thing people say about him. So if he never reached sexual maturity it was probably a big sleepover to him and he did not understand why it "looks wrong" to sexually mature people. Also the family doctor said in his book Joe Jackson had him chemically castrate Michael as a boy.

Even the name "Neverland" suggests Michael was aware in some ways he would never "grow up"
