After three months HRT and 1-2 laser sessions, I hit male fail. However, the biggest contributing factors for me were waxing my eyebrows and carrying a purse, and maybe wearing female clothes. I had this cute punky purse with me one day, but wasn't really wearing lady clothes. My hair was already shoulder-length. Even talking (briefly) and not trying to pass, I still got a ma'am from some guy. I don't think he was paying much attention, but still, I knew I was hitting male fail pretty solidly. Voice caught up after six months HRT. I wasn't trying to go full-time so quickly, but four months in and it was becoming as difficult to try passing as a guy as it was a lady. So full-time quickly became the easier and more preferable option.
