I knew I was trans and that I wanted to transition at age 15-16 I'd say, came out to parents and started therapy at age 18, started hormones at age 19, this year I'm gonna turn 20 in May, when I'll be 8-9 months on T. According to plan, I'll have had top surgery by the end of 2016 (so I'll be 21 years old at most, if everything goes as planned).
