What is gender variance?

I tend to use the term gender variance a lot but what is it?

Gender variance encompasses all expression and identification outside of the accepted binary which includes all those perfectly comfortable with birth sex but who need or want to express gender outside of its constraints as well as those who are, to varying degrees, uncomfortable with birth sex (ie.are gender dysphoric). This is ostensibly the spectrum which Harry Benjamin identified and cataloged all those decades ago.

That today I often see expression and core identity readily lumped together is why I feel some of us may have a harder time self identifying plus why some younger people may have issues regarding identification and whether or not they should transition.

For some it's been easier while for others it's taken decades of reflection but today's environment tends to speed everything up with mostly better but definitely some worse outcomes we are increasingly seeing.
