I agree with a PP about boundaries, but it's not just about personal boundaries, it's societal boundaries about what is acceptable. Since the 60s, there has been a determined effort by (for want of a better term) liberal elites to label anyone who wants boundaries around sexual behaviour as a prude. There are two options: you are either cool, modern and sex-positive, or Mary Whitehouse, with nothing in between. There is no recognition of the importance of sexual boundaries to preventing abuse, and in keeping sex pleasurable for women.
So now we have a world where 16 year old girls feel they have to accept choking and anal sex, and where millions of men feel entitled to watch children being raped online.
There have always been abusers, of course. And the pre-1960s world had some dark prejudices of its own. It's not that I would want to go back to the morality of the 1950s, but we have replaced it with something that, for many women and children, is worse.
