i can bend my fingers the other way quite far, it always freaks people out a little when i do that

my feet get hot very easily, to the point where in the summer the only "shoes" i can wear is flip flops or sandals, anything more and i feel like they're on fire in minutes

I have a few

A Dexa scan I had done revealed that I have an incredibly dense skeleton in the top 1% of the US national database. It sounds neat but it does absolutely nothing to stop all the soft tissue damage that sports accumulates.

A genetic test revealed I have the super taster gene, some things taste godly but mostly things people like taste bad to me. Coffee, beer, wine for instance are all repulsive.

I have no refractory period. I can pretty much have sex as long as I want and cum over and over again. Record for a single session was 19 with a kinky femdom I used to play with. Despite what all of those female rap songs tell you, there actually aren't very many women that are ready for Mr all night when he shows up.

I heal incredibly fast, I had major surgery and I blew past all the normal milestones for recovery.

I have central heterochromia in both eyes which I'm told is attractive

I also likely have the genes for FNSS (familial natural short sleep) which basically just means that I am genetically predisposed to only require 4 to 5 hours Sleep a night to feel completely refreshed.

• I don't get fevers. My immune system is above average, I don't have any diseases which affect my immune system, and nobody's sure why I don't get fevers.

• I have hyperphantasia, so when I imagine things, they look as real as real life, or like I'm watching a movie scene.

• I also have hyperthymia, which means I'm in a near continual state of mild mania (and I enjoy it!)

I blush extremely easily when I'm aroused or embarrassed . My previous partner used to rely on it to see if her flirting worked and even tried to push it as far as she could to see how red I could get. The answer is very, very red! Even my chest starts blushing at some point! When I have an orgasm I'll often be blushing all over my body. Apparently it's normal and I don't have any health problems...

Also my sense of smell is insane, and I can touch my nose and my elbow with my tongue.

I sneeze when the temperature changes significantly. I have no idea why.

I think it's pretty wild that the body will just accept exogenous cross-sex hormones and start using them without issue.

EDIT: well, a caveat would be that cross-sex hormones would cause gender dysphoria for cis populations, and their brains don't function as well on them, but I meant more like even a cis person's body will grow boobs on estrogen or grow thick dark hair and develop stronger body odor on testosterone. It's just wild the body is so adaptable, though maybe it shouldn't be surprising since most people have all the hormones, just in varying amounts.

I can pop my neck at will thanks to a childhood judo injury. Thanks sensei!

I also have ridiculously sensitive hearing where I constantly pick up background noise, like a radio with its gain set too high. It's hard to hear people talk over the noise of a common house fan in the room.

That's kind of crazy what happens with your ears with the pc monitor and all! Can you use over-ears headphones?

If I leave my stomach empty for too long, I can feel (and hear!) gas bubbles (?) coming up in my throat lining.

Mentally perceive sounds as color. I don't get the visual effect as with true synesthesia but more like my mind says "that sound is blue" when I hear it.

My neck clicks whenever I turn to the right.

Sneezing when I eat too much, typically 3 times.
