Regarding female people being able to correctly sex a male person maybe these links will help.
It has everything to do with recognising male body cues that are rather distinctively male and not to be conflated with 'masculine looking female'. These arguments that female people recognising male body cues are problematic in some way, ie. on this thread it is being framed as racism, are not new. But they are flawed because they rely on 'looks' and when female people recognise male body cues, they are not relying on 'looks' or 'beauty' at all.
Female people can very reliably identify a male person's sex without even seeing them. Just by hearing them or seeing them move.
Maybe this will help. These are just some of the differences in the male body due to testosterone.

Here in this Times article is a good hip alignment article.

"Biomechanically, though, she still retains distinct advantages. The athletes she will be competing against have naturally wider hips. For the purposes of powering a bicycle, the crucial element here is that they will have a wider angle between the hips and the knees — this means their quads do not work so efficiently in transferring power."
Here is a study done on faces, just to disprove this 'beauty' myth of an argument that has been posed on this thread.
https://www.sciencedirect.com/science/article/pii/S004269892200133X
Our results indicate that facial structures with full information on the texture and color of the skin are correctly classified as to their sex by most of the participants (98.4 % for Exp. 1 and 94.6 % for Exp. 2). If we do not consider versions 3 and 5 (close to the androgyne version 4), which contain a certain degree of sex ambiguity and only consider the less ambiguous versions (1 and 2 for male faces, and 6 and 7 for female faces), the accuracy approaches the ceiling (99.9 % for Exp.1, and 99.1 % for Exp.2). This is in line with previous research which observed that natural faces, devoid of any cultural signs of sex, are generally correctly categorized into their sex
I would think that results over 90% indicate a correct assumption that most of the population can accurately identify the sex of humans from faces. However, note the difference between people correctly identifying male versions of faces vs female.
The study mentions other papers as well.
I have a link stashed away that show that babies can recognise male and female faces too.
I am really not sure when people started to believe that their inability to tell the difference between male and female people through observation and hearing voices was the norm. The research says otherwise.
Nothing to do with 'beauty' and fucking everything to do with observation of distinct body cues of masculinised male people.
Again, posters need to be aware of the misinformation that has been posted on this thread .
