In fairness it was over 40 years ago!
I have not seen The Paperboy, and I know the scene in question and am aware of the "Hollywood stock" of those involved, and I know it was very risky.
But they were deliberately courting controversy whereas Ms Welch actually thought that Myra Breckenridge was going to be the film that would get her taken seriously as An Ac-TRESS. Looked at now it does seem like career suicide. 1971, anal rape of an "all-American" beefcake whilst wearing a stars-and-stripes swimming costume - it was never really going to be terribly commercial...
