My girlfriend was watching some documentary on TLC about a paralyzed woman getting pregnant. I believe that woman still has some feeling, as she spoke about feeling the effects of a bladder inflamation. So supposedly, her brain could fire up her vagina to get ready for sex (in the sense that it gets lubricated and the labia get swollen).
But suppose a woman is paralyzed so they have no nervous connection from the brain to the vagina (or vice versa). Could she still be aroused in the sense of swollen labia, etc? (Presumably via some hormonal system?)
