This reminds me of the fellow who was training his donkey to get by with less food each day and one day as this fellow was about to achieve his goal of having the donkey get by with no food at all, the donkey drops dead of starvation.
There’s no mitzvah for the average person to train himself to do without something that is required for normal people; i.e. affection between married couples in private, which is shown in our Torah. And it’s not fair to the spouse. At the end, something’s got to give.
