Most movies haven't been censored in awhile. Few years back I was on AA and saw a comedy with Andy Samberg listed. "Tour De Pharmacy" I was quite shocked at the full frontal nudity being shown on a plane. Multiple shots of men and women private parts, plus sex scenes that bordered on porn/at least softcore.
I asked AA FA and she stated they don't censor. I thought this was plus, but would've been uncomfortable if there had been a child next to me.
As for OPs requester, the lady asked, she didn't demand. I'm not sure why we need to involve FA for a simple request. Unlike politics, sex is something that is regularly censored here in US. Heck go to just about any country in Europe and you'll see nearly (if not actually) hardcore sex on TV at some point.
