I saw that on the news and a following story was flaming Sarah even though it was consensual.
Almost like the PC's do not like Sarah's tolerance of a guy who admitted doing non-consenual masturbation with other women.
I always think the Howard Stern style questions are a bit of a trap: he asked, she answered. She made it a point to say her experience wasn't meant to imply anything about other women's experience, but then the media picks up on what she said but not why she said it (i.e. he asked) and then people proceed to roast her with "why is she saying this? What is she implying?" She wasn't implying anything, just answering a question. Some even accused her of lying to herself for saying she was ok with it.
My take is that in addition to "normal" people, there exist exhibitionists and there exist voyeurs. Power dynamics aside for the moment, when the two meet, great. They have fun together. Like a domme meeting a sub. But if you force it on people who aren't into it (e.g. as Jian Ghomeshi reportedly did), then you've crossed a line.
It is possible for her to be ok with it and for Louis CK to still have crossed the line with others that were not. She's not betraying the others just because she personally was ok with it.
