Coworker P and coworker S shared an office. Coworker P got a device that filled the office with a haze of vaporized essential oils. It was sort of a large-scale vaping device, a bit like a humidifier or fog machine.
Coworker S was a married father of two who seemed rather ordinary. After a bunch of time sharing that office, Coworker S decided to transition.
So, it's just an anecdote, but I don't think I'll be taking my chances with essential oils.
Besides the fact that this language makes trans people not "ordinary", lots of people transition later in life. There are more role models and resources now than ever before, and lots of people take time to feel secure in their identity. My point is there's nothing unusual about transitioning once you have kids, even though it can be harder.
Also, elevated estrogen wouldn't make you transition. If you think you're a man and you start growing breasts you aren't going to say "whoops, I'm a woman now I guess". Transitioning is a hell of a lot more work than just deciding one day, and typically people pre-tra sition have typical hormones for their assigned gender.
