Children of age gap relationships

I am in an age gap relationship of 20 years (For the sake of the conversation and for not moving the focus to the specifics), I'm curious about what it will be like for my children as they become aware of the gap of their parents.

So, children of this scenario, how was growing up in the type of family?

Was it weird? Did you get bullied? Were you supported equally? How different were your problems from peers?
