April,
There are no rules, no fixed milestones, your transition is yours and unique. How you express yourself is a decision that is yours alone. Now that the disclaimer is out of the way - I found that attempting to scale back only led to self doubt, and was a disaster. For me it has been necessary to express femininity to be whole.
Yes it does get easier, and as your body and your mind align it becomes more and more natural. You have beauty and youth, do not fear the consequences of living authentically, but embrace the woman you are.
Peace
Julie
