i dont understand you people!
Your understanding and idea of fetishes seems flawed. There's nothing to understand, every brain likes different things, not even just in sex. Also you seem under the impression that things like leather are automatically tied to bdsm, but they're very separate interests, they just happen to very often be enjoyed at the same time. For example I enjoy bondage but I prefer it in a cute way with dresses, skirts, lingerie, etc. and maybe a nice rope or even a cute cloth to restrain with.
