MJ was chemicaly castrated as a child to stop his voice from changing by his father. He never grew up he felt like a kid in an adult's body. So he often liked to play with kids and have sleepovers. Like literally the normal stuff you did in your childhood. He never got this as a child he was on the road or on TV performing.

So the parents of these children try to get money from him. A grown man in bed with a child. And he has to settle out of court many times.
