Probably, but as I say, CSA is not exclusive to females. She may well have felt as if being a boy would have protected her but that isn't the case. It may well have protected her against whichever individual deviant targeted her but males are not exempt from sexual abuse. She has also claimed that she does not remember her trauma, so how she would remember a detail like that is beyond me.
She was a child when these alters formed I think she just didn't know that boys also could be raped.
In the video she said this about her grandparents about at 9:30 :

I think her sexual traumas started after her grandad's got sick. Her grandparents couldn't look after her anymore and she ended in a bad place with a pedo.
I'm one of those who believes she really has DID. I don't want to convince anyone but I write a list about the reasons why people believe and like her. It won't contain powerful reasons but small things which matter to ppl.
- In the whole DID community she is the only one we are sure was diagnosed.
I mean you can see she is chatting with her therapist on Twitter, they made a collab video and so on.
Btw, she will make a video with Remy Aquarone too.
-She was professionally recommended.
-You can see that her channel isn't a business.
She makes only one video in a month. Her channel is 6 yo and she has only 73 vids. It's obvious that she doesn't make it for money. You can barely see ads on her videos. She doesn't have a ton of merch. She doesn't use clickbait titles and thumbnails.
-She was on TV multiple times.
One of the documentary movies you can see Remy Aquarone who admits she has DID. I know what is the opinion of the Kiwifarms about Remy but he counts as a recognized DID expert.
-She has a psychological degree.
-She has a family and a job.
So we can see she is able to live a functional life with her disorder.
I heard her voice record about her flashback. I think even if DID really doesn't exist she has C-PTSD.
She showed her brain scan in her DID self-made documentary video. We can see the neurobiological impact of PTSD in this scan.
I mean it's another point. Even if she is lying she is lying herself too. She doesn't want to screw people over.
