when i get scared my eyes twitch.

Nothing

When I get turned on, I shake. A lot.

It's really bad and annoying

When I'm happy my cheeks do this weird thing where they lift up the corners of my mouth

go get that checked out, Adam.

whenever i feel guilty i get this horrible feeling in my throat.

When I get nervous I shake alot,like REALLY REALLY REALLY bad

I smile when I'm really angry.

When I'm awkward/shy, I can't make eye contact. And I turn red in the face.

When I'm angry, I turn red in the face and grind my teeth.

When I'm genuinely happy, I have a painfully goofy smile and giggle a lot.

When I'm lying, I bit my lip.

When I'm nervous, I get really cold and shiver.

I get really hot when I'm embarrassed or nervous and my armpits used to itch but now I sweat. I can't.

My facial expressions tend to show exactly how I'm feeling when I'm annoyed or I don't want to be bothered or something.

When I'm engaged in a sexual act my legs start to quiver.

When I'm flattered by a dude I can't help but laugh and stutter and smile and act goofy as all hell.

When I'm mad or upset I start talking really fast and highpitched and it turns into a nonsensible shriek
When I'm nervous I blush really bad and my voice shakes
When I'm talking to somebody I have a crush on I laugh this loud, ugly laugh and can't control myself.

When I am about to give a presentation , I tremble
