It's not just providers, you can also be the victim of your wife or SO. This just makes my blood run cold. Additional articles below the main story show this is not an isolated case of assault.
Also, we have the case of Lorena Bobbitt who severed her husbands penis and then took it with her and threw it away down the road--source Wiki, see below:
"John Wayne Bobbitt (born March 23, 1967) and Lorena Bobbitt (née Gallo, born October 31, 1970) were an American couple, married on June 18, 1989, whose abusive relationship gained worldwide notoriety for an incident in 1993 when Lorena severed John's penis with a knife. The penis was subsequently surgically re-attached."
