I'm gonna be honest dude. The "shorts is just over-sexualised jailbait" is a you issue, and more of a self report on the shit you watch, or you being hyperbolic. I often watch shorts and have not once ever seen anything remotely as you describe.
You get served kid videos because you watch them, which is sick of you. It's wild you'd admit that when common knowledge is algos show you content you seem to like.
This situation you describe is something I don't see a major problem with. It being yours but under your parents control and secured away unless he's present with you sounds like a responsible approach that seems uncommon these days.
I dont have any children, but I still think it's the right and responsible thing to lock up my firearms.
You shouldn't label all women that way. I'm sure you have fond thoughts about your own mother or grandmother. What you're saying basically calls them horrible people which I'm sure isn't true.
The issue in this case is that you have a man with a position of power potentially using that position to prey on women who are less able to reject his advances without potential consequences like losing their job.
I don't think it's his or anyones specific surprise by this behavior. For me, it's surprising that people seem to just let him do it and seem like it's normal, which only normalizes it further.
