My issue is that bodies are much more diverse than “male/female”. The most common form of sex confirmation surgery (IIRC) is cis men having breast tissue removed. (Assuming clothing isn’t baggy and hiding them) if you can’t tell the difference then there isn’t a big enough difference for you to care, and both of them cover some of both birth gender’s typical body forms.

Basically, male/female isn’t accurate and can be an issue with some players. A/B isn’t helpful but at least isn’t problematic.
