Your story rings many bells with me, although backwards. Through my teens I would pray every night to be a girl in the morning. And I've never liked my flat chest. I always longingly watched the girls play. (See, the same but backwards)
I put off transition for 5 decades. Eventually the dysphoria caught up with me and it almost cost me everything. Transition has cost me only my marriage, but my ex wife, may end up being a better friend in the end.
Take your time, it's your life. You'll know when you're ready, if ever. I've talked to my therapists (yes plural) about "why now." Their response "Now you're ready"
Enjoy being you. Define yourself however YOU want. Be careful of trying to please others.
