Jumped in I suppose. Or eased in quickly? In three months my breasts were poking through my shirt, my face was clear of hair and softened, fat had started to shift a bit, and I had incorporated some female elements into my wardrobe. So male fail came quick. At one point I went out in guy clothes, but carried a small purse. Even though I sounded like a guy, I still got ma'am'd. It just snowballed from there, I think because I got addicted to hearing that from people. Three months in, I waxed my eyebrows and hit total male-fail. Unless I talked, I always passed. A month later I went on a trip with a friend for a week and spent the entire time as a woman, testing the waters. Used the women's restroom for the first time (and several more times during that trip) and haven't gone back to the men's room since. Didn't have any problems so I went full-time. And I think soon after that my voice caught up. It feels like it all happened at once though.
