Does Todd Atkins believe that a woman's vagina can just close up if she's being raped? If he does, he's obviously never had sex with a woman.
A woman's body does not just "shut down" and woman do not need to be aroused or conscious for sex to take place.
And believe it or not, they can still get pregnant.
Once a man ejaculates inside a woman's vagina, she may get pregnant. Period. Being coerced into such an act doesn't rule out the pregnancy possibility. If that were so, how did 25,000 pregnancies occur from rape in one year, shown by statistics?
Some women even orgasm from being rape. Again, science: this simply occurs from the mechanics of being physically stimulated, not from emotional arousal.
