>>46816559I think maybe Psychic-type or Aura-reading could be able to "read" and notice the difference between a female mind/aura/energy/whatever and a male one. Maybe the smell too i would add. The differences between a female dog and a male dog are small but they are there; like the bone structure. If i wanted to make a fic, i would put that Male Gardevoirs are just taller with wider shoulders, but really nothing else apart from a genetic quirk that came from the Gardevoir's father-mon. So those who aren't accustomed to Garde-anatomy would get confused at least once or twice.
