Hell yeah, but I love it more going in than coming out. It's not so fun pooping it out later when my ass feels like it's on fire.
I like very spicy Texas-style chili, curry, buffalo wings, etc.
There is a limit though. One time I went to a restaurant and ordered the spiciest level of hot wings they had (10 on the hotness meter out of a scale of 10). It ended up blocking up my ears while my face went kind of numb, and the taste was so spicy that it started to get kind of gross after a while.
So I have my limits. Maybe a 7 or 8 there would have been good for me.
