I have a stunningly beautiful tgirl friend who has been on hormones for many years. Her face and body for all intents is woman, yet of late she's really depressed and has become almost housebound. She feels she's ugly and won't be seen out. If she does go out, its a masculinised version of this lovely lady......the reason...she's 6'3'' and gets made as having been a male by some people and in her eyes, thats ugly...

so by all means transition if being a guy makes you miserable, if your life is intolerable, but do be aware that being tall is akin to wearing a sign..people look more closely!
