For those who are transgender, or a variation thereof... (details inside)?

I’m looking for first-hand experiences only, please. Feel free to answer any one or all:

1. How old were you when you made the decision to transition (or at least to identity as T)?

2. If you have chosen not to undergo any medical procedures to change your appearance and/or genitalia, and your appearance is significantly different from your identity (e.g. you’re MTF and you have kept your penis, or you’re FTM and you have sizeable breasts), how do you affirm your identity as trans?

3. What were the factors that made you decide to acknowledge to yourself and to others that you are transgender (or a variation thereof)?

4. Do your parents know? If so, how did you tell them and how did they react?

5. This is similar to question #2, but slightly different: If it is not obvious by your outward appearance that you are the gender by which you identify as, do you make it a point to identify your gender (or whatever) to those with whom you intact on a regular basis?

Actually, I have a lot more questions, but this is it for now. I’m asking because I’m questioning my own gender identity.
