It's dominating the news these days, and rightly so.
With humans, for whom it is natural to live within cultural/religious contexts, questions about "natural" are always fraught. However, I will claim that sexual abuse by women and men, but more by men because of dominance hierarchies, is part of the animal side of human nature like violence, etc. Human nature contains much unpleasantness.
There are errors in Freud's Civilization and It's Discontents, but he got the big picture right. Living a bourgeois civilized life is challenging for humanoid animals and, depending on the culture, demands some sorts of instinctual restraints or constraints, at least on regular folks. The elites get away with more, and the poor folks often end up in jail.
Claiming that something is "natural" does not claim any moral valence. However, even in a Christian culture like medieval Europe the knights and nobles pretty much had access to any female who took his fancy (and vice versa, in the fancy courts of Europe - if a princess summons you to her boudoir, No is not an answer). Today in American, females teachers are routinely called on the carpet for seducing their high school students (which is not very difficult to do). For many women, "star-f-ing" is a diverting hobby, so it works both ways.
One of the perquisites of wealth, power, dominance, or celebrity is access to sexual adventure without consequences. In our culture, we consider some of it immoral and some of it illegal. Other cultures have very different rules about sexual behavior.
My point is simply that, in our society, there is and has been far more sexual libertinism, rape, and abuse at all levels of society (but perhaps most at the lowest and highest) than people like to admit or confess. Until they are caught. The unleashed sex drive is a powerful force and in people who don't care much, power, money, lust, and indifference to law or societal codes can let animal spirits loose. Attila the Hun is said to have fathered 10,000 children, which is why most Europeans claim him as an ancestor. 10,000 were not consensual, I am certain. But I wasn't there.
