If you mess up with your girl and make a mistake or lose your frame, own it. 

Apologize if it’s warranted and mean it. 

Repentance/ being sorry for someone is illustrated by your turning away from the thing that you are apologizing for. An apology is not just a set of words. Contrition is a set of actions.

Never beg. Ever.

If you’re with a woman who enjoys you begging, none of this applies to you because you’re the submissive in your dynamic. Which is fine, it’s just not something on which I can counsel you.
