Carolina,
You already pass. Any of us will be in a position where we are read as male. That is the inevitability of transitioning in this binary world. I didn't want to transition unless I could do so in full acceptance of myself. This doesn't mean I am comfortable with being perceived male, but I do acknowledge and accept that my body is socially categorized male. Transition is about embracing my femininity, and negotiating between my soul, body, and world - who I am, and how I can assert myself here best to nurture myself. This is about self care. Be gentle on yourself. You pass when you believe in yourself. And of course the way you look plays an essential role in passing but be honest about your appearance and be grateful for the part of yourself you do like. You look like a woman to me.
