Asking this as a self-described masochist: Is pain purely physical, or is there a psychological component, too. And is it inherent in pain that it is avoided/disliked? Is it possible for a person to truly enjoy pain, or is a masochist's experience with pain transformed by the fact that they enjoy it that the experience can't really be called "pain" at all?

great question -- though it's not like there is 'an' answer here, though there is much to be debated as you formulate your own anwer. For one thing one must try to separate 'the 'experience from the language we use to speak about it and focuse on the experience. And anecdotal (incl medical) evidence seems to suggest it's no uncommon for people to report things, under anesthetics of various sorts, that they are having terrible pains but somehow don't mind them. That prima facie suggests that that very experience, the painful one, doesn't have to be a cause of pain, so to speak -- which suggests it is NOT inherent in pain to be avoided/disliked. (Lnguage complicates this b/c we might choose to use the word pain in that restrictive manner and thus claim those un-minded experiences do not earn the label 'pain' -- that's a semantic choice but it doesnt seem to effect the ontological conclusion.)

hope that is helpful ...
