Marvel movies are also made to export to a global audience looking for family-friendly entertainment. I'm sure some countries' censors would balk at sexual content as much as they would disagreeable political content.
They already make special cuts for china, extended editions for BD releases, director's cut, ...
Couldn't they just make another cut for more conservative audiences that omits/tones down a few scenes?
Why would they do that when not spending any resources, time and money on having such scenes is more profitable as it doesn't appear to be hurting their viewership numbers?
Yeah checkout Chinese cinema. A woman in very modest undergarments is considered risque in the movie and treated as such.
