Since all the men on Earth became women, society has changed, more or less for the better.
New genetic research has given women the ability to grow cloned babies with genetic material from both mothers.
Manly sports like football and MMA fights still exist, but, as women, former men are now much more empathetic towards their born-female counterparts. But, deep down, men are still men. Except now most of them don't have their mighty dicks or big muscles to push their women around with.
Since everyone is female, things like nudity and free love are much more acceptable. Not to say that everyone wanders around naked in the streets or has public sex or anything, but it's a bit less frowned upon now.
All former traces of men still exist as well. Electric shavers and boxer shorts are still sold in stores. In media from before the change, people can still see pictures of men. Outside of that, the male sex is also still found in every animal except for man.
More empathy also means less war. Aside from all these minor changes, the human race has more or less remained on the same steady course it has been taking for the last couple of centuries.
Now, let's say 5 years after the initial Change, who should we follow in this new world?
