The act of straight sex confuses me! Could someone explain it to me? In detail? Please?

If we look at the act in more detail (skip this parag if you can’t take it), PIV is a man mounting on a woman to thrust a large member of himself into her most intimate parts, often forcing her to be entirely naked, banging himself against her with the whole weight of his body and hips, shaking her like he would stuff a corpse, then using her insides as a receptacle for his penile dejection. How is this a normal civilised, respectful way to treat anyone? Sorry for the explicit picture, but this is what it is and it’s absolutely revolting and violating. The term “fuck you” is not an insult for nothing, men know why—it’s the worst thing you can do to a human being.

From "PIV Is Always Rape, Ok?", a blog post by a crazy person that ten different people sent me the link to over the last two weeks. It gets even crazier in comments. When someone suggests that women who like PIV sex and enthusiastically consent to it aren't actually rape victims... and that to describe them as rape victims does a disservice to women who have been, you know, raped, the blogger responds...

To be a rape victim isn’t a competitive elite oppressed status reserved to a special few women, which loses in specialness as the number of rape victims increases.

Um... wow.
