how should i bring it to my gf?

hii everyone, sorry in advance if this isnt the correct sub to do this question.

So i(20m) want to ask my gf(21f) if she could have a more domiant role when we have sex, she already is bit dom but she gets softer as we are doing it, i would love if she could be more dominant when she feels like dominating. being more strict and use me as the sub i can be/am, i want to pleasure her, want to be used by her and so on. She dont watch porn or consumes any content like that, she reads smut and thats it, i was thinking about sending her a link/storie that contains femdom so she could read it.

Is this a good aproach? and am i being too self centred?

sorry for the misspelling xoxo
