This becomes extra twisted if either one of them is already dead. Like, maybe you wait because you missed whichever one was dead and talking to them again is something you never thought you could do? And like, is the other one trapped in a decaying body in a grave? Or what if they were cremated? Does the living ones mind go to the afterlife or stop existing or whatever? What would that do to them when they came back? If one was cremated and you rubbed the ashes on your fanny or something would that count as sex? I mean- Bill Clinton right? What even counts as sex?
My answer is always death
