The only way a sexless marriage is unhealthy is if one of the partners wants sex. If neither is interested, it's not a problem. I have known couples who need sex every day, and I've known couples who have rarely have sex. Both happy. Mixed it up and swapped them around? Deep unhappiness. Stop projecting your preferences onto every other human: the amount of sex you prefer in a relationship is unlikely to be a perfect match for everybody. You especially need to be wary that if you are inclined to have a lot of sex and your partner is not, you may unwittingly be forcing them into something they are not comfortable with, and as a result making them deeply unhappy. It's not a trope. It's just basic human understanding.
