I'm a 17 year old male and about 45 minutes ago I tasted my own feces and am now feeling very sick
That sounds disgusting. Why would you taste your own feces?
I ate some bad cheese earlier today and I just decided I wanted to taste feces too. It triggered my gag reflex.
Eating your own feces is a very bad idea. It is extremely unsanitary, as well as disturbing behavior. There is a lot of bacteria in feces that can make you very sick.
But I'm fine just queasy.
You're not fine if you're queasy. Your body knows you ate something unsanitary, and is working to get rid of it. You should consider getting medical help if it doesn't stop feeling bad soon.
