As I said last time it was simples when I was in infants and juniors but things went rather awry.
To really begin to understand where everything starts from you need to understand that exposure to and promotion of a anti male agenda in my teens didn't just mess up my sense of identity as a male but also pushed a unease about my own body image, seeing it as less desirable or even disconnected from my own sex.
You hear the same things today where people argue that sex isn't determined by hormones and your actual sexual organs but I started recently questioning much of that.
If I took my underpants down you would see the sex organs that are part of my body and everybody present would say inequivalently I am male because I have them and that is after all just what happened when I was born: in no uncertain terms society was told I was a Gender- Boy- and until all this other stuff came in did treat me as one valuing it.
