Sex is often a requirement in modern relationships because most people, in my experience at least, are in fact mortified at the thought of having true intimacy with someone because it means that they must expose the worst in them, which forces them to expose themselves to themselves, as well, often for the first time. — Heister Eggcart
You're saying that many people want to avoid intimacy, therefore sex is a requirement in modern relationships? Do you mean
sexual or
romantic relationships? I'm pretty sure that sex has been essential to a very large portion of human relationships for a very long time. And you assume, without any justification, that sex is not a part of being intimate with someone, but is rather a way of
avoiding intimacy. As I think this goes against the experience of most people--certainly my own--I think you have to properly explain what you mean.
I'm open to the idea that there might be a new and increasingly widespread way of relating to people sexually that excludes intimacy--a kind of relationship that we might call pornographical, both because it is primarily objectifying and also because pornography increasingly shapes our sexualities--but this is a long way from saying that sex
per se is an avoidance of intimacy.
This is one reason why successful marriages in the West have rapidly deteriorated because spouses realize too late that they do not know who really is next to them when they go to bed each night.
This is simply not credible. Do you think that when divorce was taboo and women were subjected to the authority of the husband, "true intimacy" flourished? Do you think that when marriage was more openly and uncontroversially about property and status, couples really got to know each other? Do you not realize that it's only recently that romantic love has become the primary reason for getting married?
Modern relationships have gone about creating a culture that overemphasizes the gruff physicality of the body, and therefore of sex, as being the foundation for the growth of a relationship between two people. No one gives a hot damn about virtue, only whether you like fleshy dicks or plastic dicks, if you like it in the butt, in the mouth, or in the nose, whether you like black hair over blonde hair, tan skin instead of pale skin - honesty, though? Attentiveness, understanding, compassion? Meh.
This demonstrates prudishness and little else. You do realize that attentiveness, understanding, and compassion, along with gruff physicality, are often essential to good sex?
