I disagree. I think there CAN be a very intense overlap between feeding and BDSM. And it can work in lots of different ways. The stereotype is feeder=dom/me, feedee=sub, but if you look back in the threads on the BDSM forum, you'll see one about dom/me feedees, which makes perfect sense to me.
While I'm very conversant with BDSM communities and practices--you can't be a lefty in the SF Bay Area and not have lots of friends in those scenes--I'm not especially interested in more than a bit of light play.
For these reasons--a) it's very movable, and

not everyone feels it--I don't think it's *inherent* in feeding to be overlaid with BDSM. Rather, I think power play is a common part of sexuality: for some, a major component, for others of us, a minor one. And I think
that's why it maps so readily onto feeding.
