You know what, a lot of people get weirded out by necrophilia. But I'm totally fine with it! My gorgeous corpse will probably get laid more than I do. Once that off-putting personality's out of the way, "it's on." Or so I would suspect!
And that's fine. I say to the world, "knock yourself out!" My organ donor card explicitly states "NO organ doning. YES necrophilia." Under which I have handwritten, "Bring it." In fact, the whole reason I refuse the organ doning is I'm worried it'll cut down on my chances of getting laid, postmortem. There's only ONE organ I want to be "doning."
But "Not so fast!" You say: "It's not so clear-cut. There may be gray areas involved: what if you're in a coma? What if you're in a persistent vegetative state?" The answer is still yes. Oh! God! Yes!!
It's a heartbreak, in this life people think they're immortal. They leave these decisions unmade. It's so important to let the world know what your wishes are...before it's too late to say. I have also made my wishes known: do not unplug me.
But I guess in at least some instances, that's going to be up to the other person involved.
