Cameron feels like a real girl. And your body doesn't know that hers holds together with metal, no bones beneath the flesh. How can the heart be cold when the skin feels warm? Structure is immaterial, nothing to do with desire. It's the mind that turns away, your mind that breaks.
The mind says, this is fucked up, but the body doesn't know any better. Doesn't know this isn't real. Cameron looks like a real girl, smells like a real girl. Sometimes even acts like a real girl.
Anyway, you love her.
