An interesting discussion here...
I doubt that there is one marriage on earth where the two individuals have libidos that are the same, or are in sync. This is just a fact of life.
Each couple has to work this out between them, with understanding and acceptance that marriage itself is a lifelong opportunity to learn how to better show love and affection to each other.
Love is action, not feeling.
Libidos, thermostats, affinity for dancing, appreciation for the other’s parents.
It’s a miracle any of us stay married.
