Okay, I'm a biology major and this just fills me with questions.

Does Ratchet have a spike as well or does he just have a robo-vag? :D If there is a difference between the two, does that mean there are robotic sexes even if they don't have genders per se? Or at least there is only a small proportion that identifies as female.

Feel free to ignore me. My questions were just driving me insane. << >> <<

Excellent story.
