Probably this will be the phrase my mom will say to me when I come out to her: "but you don't act like a girl"
This is a hard thing to answer.
It is not exactly evident that I act like a girl. I do a lot of things as a man is supposed to do, but I also react and do lot of things as a girl would do.
I can do small repairs at home, I care a lot about my car, I played with plastic soldiers when I was a kid...boy things....but I am very emotional and cry at every sad or happy thing that happens to me (including movies), I love to cook and I am always helping my mother at the kitchen, I played with stuffed animals and other girl toys when I was a kid...girl things.
This is a crazy mix...But I have one explanation.
The way I fell was kept deep buried in my mind and was repressed for so long...I tried to be what was expected of me, I tried to be a man. I tried to like boy things, like sports, drinking and talking about women...but I failed miserably at that because that is not who I am.
I was more of the lonely guy that spent hours reading and studying, having almost no friends and that walks looking down. I am not effeminate... except by the fact I usually sit in a more feminine way and sometimes I think my walking is a bit girly.
So, "but you don't act like a girl". I don't act like a girl because I couldn't...I am a girl that tried to learn how to be a boy. That wasn't working and I closed myself in a shell to avoid being hurt.
