Shame is an emotion which is driven entirely by community influence.
As a community (especially in the 'states), we shun sexual contact in general, but especially in odd situations. We are taught from a young age to fear and loath sexual fetishism and adverse behaviour. Fetishists are often lumped in with dangerously disturbed minds, such as child molestors and violent criminals.
But that simply is not the case, at least as I have found it (I may be new to posting, but I have lived as a lurker in the community for years). Fetishism is not dangerous, and it is society, not any higher power, that has taught you to be ashamed of it. That same society compells you to believe many things which are fundimentally incorrect. Should you accept it without question, you are surrendering your power and freedom, and nothing good can come of that. The most important thing in life is to question society, your peers, your elders, and yourself. Heck, question me, and the advice I give you now. We are born with the power of reason. Why should we not use it?
That said, I suppose some people in the scene get turned on knowing only that what they do is taboo...a sort of excitement value, so, if that's you, than ignore what I said, and go for it on your own...
