Is there a difference between “sexualization” and expressing feelings of sexual attraction (instinctual)

Certainly the feeling of sexual attraction isn’t wrong so to speak because it’s a natural feeling and a sign of hormonal health and sex drive biologically.

Given that free speech exists and censoring your thoughts and feelings to accommodate others thoughts and feelings isn’t legally required (unless it’s to the point of harassment).

Tell me is there a difference between sexualization and expression of feelings of sexual attraction? If so what are the differences?
