With regard to Viral Worm and futa prostates:
The bladder is in front of the uterus in female anatomy, and the prostate is attached to the urethra. As such, wouldn't the prostate be in front of the vagina and therefore better-stimulated by vaginal penetration than by anal?
(The Skene's glands, which are the normal female homolog of the prostate, are likewise in front of the vagina.)
