If our sensory pleasure is fulfilled with our life partner, then we should restrict our craving with that one choice, and focus on our duty, otherwise, it will be considered as an animalistic behavior and we will have to pay a hefty price for that.
I agree with you. It's one of my principles being a married man, and even without a child, I wanted to be loyal to my wife.
That's lovely to hear, hope you will have a child soon.
