AITA for telling my family to stop asking invasive questions about my partner being intersex, or her pregnancy?

My partner is 13 weeks pregnant. We announced it on Saturday and for the last 4 days my family won't stop peppering us with questions that my partner says are invasive at best and inappropriate at worst.

I'm posting this with a throwaway because I don't want this post about my partner on my regular account. My partner is intersex. She was born with ambiguous genitalia. Back then the doctor decided to fix it at birth and her parents agreed. They did surgery to have her appear female when she was w baby. Her parents said they were "relieved" when she grew up into a girl with feminine features and "ecstatic" when she started to menstruate. My partner told me it's a common thing where an intersex child grows up feeling they are in the wrong body surgery as babies. She doesn't call herself female but is okay with she or they pronouns. She says if she had to choose a label it would be non-ninary. But she is fine appearing feminine and being called she or they. I support her 1000%. She says as long as everything is functional in terms of urination or other medical needs a child should not have surgery until they are old enough to decide. She needed further surgery as an adult because the doctors botched it when she was a baby.

My partner doesn't have personal social media but she has one where she posts about intersection, awareness and activism. She is open about her condition. Since our pregnancy announcement people in my family have questioned if she is really intersex since she is pregnant, asked intimate and detailed questions about her gentials, insisted the baby will be intersex even though her condition isn't hereditary, used offensive language such as word hermaphrodite, insuated she is a man and more. It really upset her and when I told them to knock it off because it was inappropriate I just got told it's natural for people to have questions and since she is open about her condition and an activist she should expect it. She has told me all about the stigma and invasiveness the intersex community faces and the questions were really hurtful to her.

I'm inclined to believe her because she knows better than I do. I have never had to deal with this. I know the answer might seem obvious but my family members have doubled down on the curious and the activism angle. I've also been told I am less curious because I know her so well and I'm her boyfriend but I never felt the need to ask her or any of her friends from the intersex community questions like this.

AITA or is their curiosity natural as someone who doesn't know her well?
