As a female in this society - you can be anything you like. You don't have to be mellow, you can be kick-ass no-nonsense clean-shaven, accepted as a peer by guys and still have all of your options open.
As an FTM, you might be accepted as a guy (with equal amount of hard work), but your options would be more limited - you won't be 100% male functionally, nor being able to present as a female. I hope you know what I mean...
So, if you want to be a guy now - go ahead, bond that chest, go to gym and pull the weights, join some good mma gym, get a part time job as a construction worker or car mechanic... You don't need T, or to shave regularly to act manly, manly behavior is what makes a man. Go for it now, try it as much as you can, but keep your options open until you're absolutely sure
