What is a furtive fetish? Is it a sex fetish that involves clothes being on?
 

I think I may have a very strange but not weird fetish of women wearing clothes as opposed to nudity. I don't mind the nudity. I just don't get off on it. Is this the meaning of "furtive"?

No..........

A simple Google search would tell you that the definition of the word furtive is"

1. Attempting to avoid notice or attention, typically because of guilt or a belief that discovery would lead to trouble; secretive.
2. Suggestive of guilty nervousness.

In regards to sex, it would seem that it means sexual encounters that are done in secret.

No.. its nothing of the sort patton.
