Man, this brings back a handful of fucking weird memories. Some of my boyhood crushes bothered me for so long it was borderline creepy.
Years later I was studying psychology and some of this shit popped into my head. Kelly kapowski from saved by the Bell and and couple of Disney Princesses definitely sprang to mind.

My teacher pointed out to me the fact that Disney was involved in a pretty public scandal involving sexual words and imagery in their media.

We then discussed the fact that as humans we are sexual beings. And while monsters will sexualize children, it's important to be aware that we are sexual beings and therefore susceptible to manipulation, even at an early age.

Take Aladin for instance, Disney placed subliminal messages into their soundtrack (all good teenagers take off your clothes).

Or the lion King when Timon and Pumba roll down a hill into a patch of flowers and purple smoke rises to form the word "sex" on the screen for a moment.

If the kid can read then this type of nefarious shit has a real chemical effect on his or her brain which might just manifest as a deep obsession with one of the characters and even fuck with their sexual development later on.

Something to consider maybe when choosing what your young ones have access to.
