Can you be raped to death? Yes. Aside from the obvious violence involved when raping someone (especially an unwilling male), when someone is anally raped there is a small risk of tearing a major supply artery to the colon and the victim could bleed to death. This risk increases with age as the colon and anal wall becomes thinner (often leading to hemorrhoids). Sodomizing a resistant victim can cause major tearing and blood loss. It is a risk for both men and women.
Use lube and don't put overly hard are large things in there. ;-0
