Why do I have fetishes? Because they feel GOOD. I don't know how the fetishes form, but people maintain and practice them because they get enjoyment out of them.
I guess beginning to experiment at a young(ish) age, having a long-term girlfriend that was "Miss Missionary" and free access to the World Wide Web opened my mind to a lot of the stuff out there. BDSM (switch), Bloodplay and Latex/Leather/PVC to name but a few of the things that I'm into.
Mind you, I think partly the reasons for these are that I am really into Goth chicks (being metalhead/Goth myself) and these fetishes tend to stack well with the mindset of those women. So they may or may not help me to end up in bed with them (if you are "compatible sexually", as in having roughly the same fetishes, then you may be chosen over someone as good looking, but otherwise not as interested in the same things as the woman).
So really it all comes down to our primal instincts of trying to attract a mate; either through choosing someone based on a certain physical characteristic (hands, feet, ass etc) or as a method of "one-upping" a rival male.
+EDIT+
I thought I'd better add, since it's come up a couple of times (post after this, for example) that -personally, I guess I can't speak for all- having a fetish doesn't mean I can't "get it up" in a situation not involving them - an attractive woman still has the same effect. It's just I believe the fetishes enhance the foreplay or the sexual experience, as well as being something sensual that increases the bond with your partner, hence leading to "better sex" (not just on a physical level but a psychological, and perhaps spiritual for those inclined, one as well).
Maybe some people can't get it up any other way, but I'm not sure any "fetishists" I know would agree with that. Or perhaps that it's just because we're into some wierd stuff and tend to keep it under wraps on one-night-stands and short-term relationships, hence can still find arousal in "vanilla" sex.
