I will never "pass" And I think trying to be feminine to prove some kind of point is no different to trying to be masculine. It's trying to prove the same point. Because it matters to you what other people think more than what YOU think.
No one in my area doesn't treat me as me, though. Not because I've tried to blend in and be inconspicuous... because that's literally never going to happen. It's because I've been all about "Who you are is how you are." There is no way on God's green earth I'm going to look like your average woman. Never in a million years. But.. there are myriad different facets of men and women. If you're good about being you, and you're secure in who you are... go fix truck engines... go make fashion catalogs... don't let anyone tell you that you have to do this, that or the other. Who we are is how we feel. It's really that simple.
People try to be feminine, masculine, everything in between. When you try to be something you ultimately fail. Don't try... you get way better results
