I like to think I'm a ler, but my boyfriend usually ends up turning me into a lee... which is annoying... but fun. So on that basis, I suppose I can't call myself a 100% ler.
I would most certianly call it a fetish... I'm not sure what else it would be referred to as. Of course that's not what I've always known it as, it wasn't until I was older and the word fetish found it's way into my vocabulary that things started to make sense XD
