Whenever this question comes up (and it does regularly), there's always this "well, some people want it three times a day, and others would settle for once a week."
SETTLE for once a week???? Some here would KILL for once a week!
Making a comparison between once a week and three times a week is hairsplittimg.
How about once a YEAR? Once every FIVE YEARS? Once every DECADE?
Can we all agree that THAT is not normal? That that is NOT a marriage?
It's not just a question of "getting needs met"-- if MONTHS go by with no sex, no kissing, no groping, no cuddling... can that really be a marriage? Where is the "two bodies becoming one" in that scenario?
IMHO once a month is the BARE minimum to be in the normal zone (yes, the dreaded "N-word"!)
