Angelina yes, but not every metal is bdsm , or would you call a saw a bdsm ?
Please consider my answer in the whole discussion. I was not talking about metal at general I was talking about the restriction to tough yourself at you bust and sex. I also not understand piercing at it is as bondage or only BDSM related. For me it is jewellery other could use it for kink. It always depends on the point of view.
