Given sociology cultural trends among millennial and subsequent generations it might start happening on its own.
I doubt it. I suspect there is a huge gap between the politically correct gibberish that those in their early 20s tolerate and what they will actually do. It's wired into the normal 98% that we are not attracted to the same sex. Even if you put a nice dress and longer hair on a guy, it's still a guy - and the attraction level is zero.
"Some Like it Hot" was funny, but how many men watch it and think Tony Curtis and Jack Lemmon look hot (not even compared to Marilyn Monroe, just attractive enough to take home after a lot of drinks)?
