What Bianca said.
Also because we were raised as boys and constantly received subliminal messages from our parents, friends, society, the press and TV that boys being more feminine is not to be encouraged. Until fairly recently even the medical profession thought it was an illness that could be cured. There are some that still believe this. We were conditioned to believe we are not normal, and at all costs mustn’t show ourselves to the world.
Self acceptance that you are perfectly normal and entitled to be yourself in public is the key to gaining the confidence to get on with your life. There are some boundaries I suppose, so some secrecy is often required, but there are times when you can get out there and enjoy being the girl you are.
I go out with my dog 3 or 4 times a week fully en-femme. I have not yet had any bad reactions from others. On the contrary, I often get smiles, otherwise either they don’t see me or they do but don’t care.
