I think OP’s point is that there is plenty of questionable media on Tik-Tok.
Your point about what they like is irrelevant to that point.

So if OP is seeing "loads" of sexualized content, it's because they spent enough time watching sexualized content before swiping for TikTok to think that's what they want to see, and ensure they see more of it.
Even if the picture you are painting of the previous poster is accurate, being horny once in a while is by no means justification for an endless stream of sexualized content.
That's not a neutral quality of the system, but a deliberate feedback loop establishing an addictive behavior. We already know the shortcomings of the human condition and should ask for less footguns, not more.
