I don't even fool with Tumblr. Just seems like a big pissing contest for the young transguy community. Like others have said, you really can't guess what hormones will do for you personally. If you feel that medically transitioning is right for you and will lead to your happiness then I wouldn't slam the door on it based on fear. I would suggest finding a therapist familiar with lgbt issues and exploring your feelings on it.
No, everyone doesn't move away and start a new life to transition. I did but that was about 13 years ago. Acceptance was nil back then. There really are no rules to how you should transition. It's your life and your journey.
