@COSMOSUNIVERSE girls, women, females, it's a chromosome thing actually. One gender will have x chromosomes while the other will have x y chromosomes. You can cut off ones turd, hormone him up until he grows chesticles, implate an apple bottom bum, botox his lips, but in the end you still haven't changed the gender at all cause the chromosomes will still be the same as they were before. When a scientist observes IT, the he-she, the results will still be the same as IT was born as. If a guy wants to identify as a girl, that's fine. But he's not.
