Why doesnt my email autopopulate on my phone

When there is a form or area asking for my email, it will offer up my sons, mothers, or even my work email but never my personal email. Even as I start typing it, it brings up my sons emails which have the same last name. I end up having to type my entire email address every time.

My email address is in my contact card and I have gone to settings, safari, auto fill to ensure it it set to my info.

It still pulls up other email addresses and not my own.

Exceptionally frustrating.
