The Short Answer

The molecule that causes the sensation of spiciness is capsaicin, which binds to the nerves responsible for registering heat and more importantly pain. This causes these nerves to fire, making us feel these sensations. In response to pain, our bodies release endorphins, which help to nullify the pain and create a mildly pleasant feeling. It is likely that we are attracted to spicy foods for this reason, because it creates a mild euphoric sensation as a side effect of the pain. Of course, the pain response can override the numbing effect of the endorphins, so we have a certain threshold of tolerance, which can vary.
