Female readers of reddit, need a little help

I am an guy and my partner likes to read spicy smut books and also likes the male protagonist and his characteristics. So I was thinking maybe I should read few of these books and try to learn form it and implement it but don't know which books to start cause some books display men with very high expectations, so are there any books with realistic desirable male that you would like you see in your partner. if yes then plz do recommend it, I would like to make my partner happy by this 😅. Thank you.
