This would be my advice: "Master, I do not want any more children and I hope this does not come between our relationship."

This is a child, not a new toy or a type of play you haven't tried before that he can ask you to try and see if you like it. You stated you have already made the choice not to have any more children based on the reasons listed in your post. You've answered your own question.
