Even the thought of the act is disgusting. Do people truly make love to corpses in real life or it's just a movie prompt. I seriously doubt any sane person will want to consider such an act. But then, we have so many sick people out there.
In fact, we do not even suspect how many sick people we have. And the fact is that their number is growing. They were before, just hiding well. Look only at the increase in crime in the field of pedophilia and everything will become clear.
