To expand a bit on what Byblos is getting at, if you are a libertarian, then there's very little you can say for or against pretty much anything when it comes to sexual ethics. So long as two adults consent, then whatever! Society may impose the idea that it has to be in marriage, or you may say that the Bible insists on that, but shy of really stretching a few verses really far out of context, I don't think that you can make the Bible say anything about this particular subject.
If, though, you adhere to natural law (which I think we ought to), then you can say a great deal about this. There may be debate among nl theorists about particular issues, but at least you have something other than personal opinion to go on. It would seem to me that to the extent that any given fettish aids and promotes (or even is neutral to) the intended end of the sexual union, then there's nothing wrong with it. To the extent that any fettish frustrates and negates the intended end of the sexual union, it is wrong and ought to be discouraged.
So, with Byblos, I would
strongly encourage you read
The Last Superstition. Agree or disagree, at least you'll be introduced to a framework on how to think about this.

And
that, brothers and sisters, is the kind of foolishness you get people who insist on denying biblical theism. A good illustration of any as the length people will go to avoid acknowledging basic truths.
