Hi Jessica,
I didn't go full time because it was required of me, it just happened naturally. One day I just ran out of sh^ts to give about what anyone else thought, and that was that. I had been processing a shot my therapist took at me a couple of weeks prior, "If there was nothing stopping you, why would you not just be Jill 24/7?" and realized she was right on the money.
The fact is that once I owned the female presentation, I became much more comfortable in my own skin that way and I NEVER wanted to show myself as a guy ever again.
If you just dress the way you are most comfortable presenting yourself, you may end up full time sooner than you think.
