Agree on your last sentence. I think one of the big problems is that women as a whole are disproportionately over sexualized and when they are sexualized, it tends to be a lot more blatant.

There absolutely are plenty of works of media where male and female characters are both sexualized. But there's also many where only the female characters are notably sexualized (or are so damn heavily sexualized that the sexualization of the male characters pales in comparison).
