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.
You probably just have a little bit of an anterior pelvic tilt. The boney prominence that you are talking about, the one that is more commonly visible in women is just the iliac crest.
Everyone have them, but your weight and pelvic tilt determine how visible they are. Women typically have up to 4 degrees of anterior tilt, while most men are in a more neutral position.
Men can have anterior tilts and be perfectly healthy, but It can also be a symptom from anything from bad posture to a limb length discrepancy. It should be fine, but I would consult a physician if you start losing range of motion or start having hip or lower back pain.
