Other comments aside, humans have at least 4 different kinds of pelvis shapes (Caldwell–Moloy classification). If you decide to look further into the research, we actually have no idea which pelvises are most common for any sex. Any research done has largely been "which best for woman give birth" and that's it.

We have no data to give a proper average of what should be expected for those assigned male at birth. We have no data for those who are intersex either but worse because even many modern practices do their best to hide everything.

No idea where you live, but to give you a start:

Since very few people are educated in seeing that, it continues this terrible cycle of fear and assumption.

Pillowfort and Dreamwidth come to mind. Pillowfort designed to be based on original Tumblr. Dreamwidth based on LiveJournal.

Never heard of this one and it's title and your summary has grabbed me. Will check it out~
