I know I'd be considered one of the 'taller' FTMs because I'm 5'7", but in my area the women are just giants(must be the chemicals). Before I used to be so self conscious about my height but then I realized that people don't really care as much about that as they care about how you present yourself. Not only that, but being short can have advantages.
You might need a ladder for some things and you might not look necessarily intimidating by your height alone, but generally speaking, the shorter you are the longer you can potentially live because your body doesn't have to work so much, getting everything out and in to your body. If you're skinny or fit, you'll probably be quicker, not necessarily faster.
I kind of like being on the short side. It makes me feel a bit unique and I think it'll look cool on me, when I start working out on T, to be that shorter guy with the muscles.
It's really just about your presentation. Don't do the small man syndrome, that wont help, just be you. The man that you are and no one will doubt.
