Fuck, you just reminded me of my first real life troon encounter:
I once met up to hang out with a person I've known for several years online. Only
after the meetup did I learn from others and the person himself that he's an MtF (he assumed I "always knew"). Now, at the time of the meetup nothing stood out too much to give any obvious clues that he's a troon - he looked female, sounded female, the body shape might've hinted at it, but I brushed it off as unfavorable genetics. But looking back at it, there was one major thing that stood out, the thing
@AfghanBlue mentioned - it's the weird "burnt" smell the person had coming off them.
Usually when you imagine the body odor of a guy or a gal it's more or less consistent, but that person didn't smell anything like it, and I wasn't intentionally sniffing them or anything, the body odor was just
that strong even while just taking a walk outside (I was physically taken aback by how
saturated their room was by the stench when I stepped foot into it). The smell didn't seem like something a
normal human should smell like. It's hard to describe or even compare to anything. The closest comparison being a smell of something burnt as mentioned earlier - burnt hairs, maybe? Anyway, they did hint it at the time ("People say I have a pretty peculiar odor haha"), but I didn't connect the dots. I was surprised to find this is not a one-off thing for troons, as evidenced by
@AfghanBlue 's story.
My best guess would be that person's natural hormones go so out of whack from all the medication that the body starts secreting who-the-fuck-knows what, which leads to these hard-to-describe, nasal-cavity-assaulting odors.
