Yes. It is my position that sexual relationships are unique, that in fact from an evolutionary standpoint the rest of our lives, all our thought and language, our physical being, our emotions, our desires, our culture and our abilities all exist only to serve the sexual relationship.
Interesting ... and far more extreme than I was expecting.
You are arguing that every thought, expression (linguistic, cultural, artistic, mathematical, philosophical, theological, sociological, etc.), desires (such as for food, warmth, clothing, physical and financial health, family, friendship, prestige, acknowledgment, self-development, etc.), abilities (physical and mental), emotions (anger, fear, hatred, love, etc.)
all exist
only to serve the sexual relationship.
How does friendship (absent sexual desire) exist only to serve the sexual relationship? For that matter, how do calculus, coal mining, cancer research, cartography and calligraphy exist only to serve our sexual relationships?
