Just make sure any woman you want to date is more physically and sexually attracted to you than vice versa.
Test the limits of her sexual attraction. She has to be willing to do almost anything at any time.
THIS! Yall can talk all that shyt you want but the fact of the matter the only way to guarantee your wife wont step out is if there's absolutely no way she can do better then you
Like the saying goes, "If you want a happy life, marry an ugly wife."
