Coming from the point of view of a 76-year-old male who has been married to the same woman for 48 years, I agree there is a certain truth to this post but it does not tell the whole story. It is something of a generalization. Every person on the planet has differing needs at different times of their lives and just as every person has a unique view of the world through their eyes, so is every relationship unique.
My wife and I achieve a high degree of unity and sameness of being by taking long walks and hikes. Just being in each other’s company and chatting about the kids, grandkids, social issues, our life together and politics provide a high degree of intimacy. We have differing points of view but there is comfort in knowing each of us is not coming from a position of ego. We have nothing to prove.
This sort of intimacy takes time to develop. It is almost a melding of two minds, something rare in newlyweds, due I think to sex being the overriding distraction. Once you get the need for sex out of the way, (not the desire) there is a certain broadening of the mind and the mind is open to a higher degree of mental intimacy. As is said: “life is a journey”, a journey providing new ways of looking at things around every corner if the mind is open to these experiences and is willing to learn from them.
