I was assigned male at birth but have increasingly started to notice over the years that other guys don’t have a big notch on either side of their torsos like I do. It’s my pelvic bone. I would go to a doctor to see what they had to say but they’ve seen me plenty of times and said absolutely nothing about being intersex and now I live in a rural conservative area and they don’t seem to diagnose the same way in hardly anything that is a conservative third rail. I just seem to have a really wide pelvis just like a female. Everything else seems male. I am a very normal weight so it’s not fat tissue - its clearly bone. I just feel gaslit over it and have been trying to gauge perceptions people have of me in my life in order to get on with things. I hate to turn to the internet but this is driving me crazy. I need something to work with, somewhere to start.
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.
