Flaming_Redhead mentioned lip sewing and other activities, and she is correct.

I straddle the fence between the body mod community and the BDSM community, so hopefully I can tell you a bit.

If you go to www.bmezine.com and look under Events (on the right hand column) you will see suspension events. Many of those include things like nailing, lip sewing, blood play, and play piercing. No snuff or amputation, but a good bit of minmually harmful bodily harm. The body mod community (like the BDSM community) is one of those things where you kind of have to "know a guy," but if you hang out long enough I'm sure someone can hook you up at a suspension con.

Good luck!
