My biological sex is intersex.. my gender, however, is female.. My transition had little to do with my biological sex.
I do believe some people spend a lot of time, even their whole lives, looking for justification of who they are..
The quicker you accept you and (dare I say it) even start to love yourself... the quicker you will get on that road to happiness.
Societal acceptance of gender incongruity is a positive in this sense. The 'less scary' or unpredictable the end acceptance and integration is the easier it is to make that choice to be you.
With every choice there are losses and wins.. And my transition has lost me a home and marriage (of 30 years).. but I have never been happier than I am now and never felt more alive.. I would strongly advocate to stop looking for excuses and start looking for truth.
