My stomach has never been the issue with spicy food. The issue is when there's too much capsaicin, it is just agony in my mouth. It makes me fucking hiccup. And due to the physical properties of capsaicin if the food is too spicy every bite just makes it worse and the sensation takes forever to go away even while drinking milk.

I really do not get why anybody seeks it out outside of some perverse "dudes rock" self flagellating thrill seeking. Things taste better when you use peppers that have flavor other than "ow"
