I'm looking for two words: Specifically, is there a word to describe the activity of eating or being compelled to eat something despite its hot temperature or spiciness? The second word I'm looking for would describe same concept but at a more general level: a word for doing something eagerly despite the pain that it causes because it feels so good.
I'm looking for a single word, but idiomatic phrases capturing the same meaning would be helpful too.
Edit: Some clarification; while masochism is pretty close, per ermanen's answer, the word I'm looking for isn't about pleasure from pain, but pleasure despite pain. In other words, the hypothetical person is compelled to eat the hot food (temperature) because it tastes so good, not because she derives pleasure from the pain.

It is called benign masochism or hedonic reversal.
Also, hedonic reversal applies to enjoying horror movies, sad movies and roller coasters as well. Further reading: http://journal.sjdm.org/12/12502a/jdm12502a.html
In general, it is masochism but the word has stronger connotations as well.
