I've never tried that as a new year's resolution...but I have tried to achieve new records of going without.
Right after our second child was born, my wife and I had very little, umm...time for that sort of thing. Plus, my wife had no appetite whatsoever for it either (understandable).
So I held off a week, then two---before becoming infatuated with all things sex. I might have well been a Victorian prude---even a bare ankle turned me on. I felt 18 again....but there is a downside---the so-called "monk's" or "priest's" disease. Google it.
20 days......Not going there again.
Instead, I resolve to drink less caffeine. We'll see.
