And what dictionary is that in?

Because the three I checked do not show it

The fact that one can find an s and m definition somewhere that has existed for as you say decades does it make it common use age nor normal language

Didn't say any of those things, but it's common enough to have encyclopedia definition if that is what you're really looking for. And simply knowing about it is not an indicator of being a partaker, any more than knowing about homosexuality makes one a partaker of that perversion. Stop trying to put words into people's mouths.
