Do I really need another reason not to get married? http://news.bbc.co.uk/1/hi/health/4790313.stm The researchers credit evolution, pointing to animal studies. I had always presumed that falling sexual interest in a partner was a social phenomenon, caused by emotional differences and neglect, but perhaps those are merely byproducts of a biological need that is going unsatisfied. I've heard elsewhere that married women regularly fret over the fact that they will never feel that "falling in love" feeling again, and that this is why they like watching romantic films. I don't think men worry about that and that this is also a biological characteristic of women and their mating practices. Male biology may prioritize a high amount of sex in the long term while female biology may prioritize a long term sexual diversity. Are our social structures at odds with our biology? The same article mentions that women consistently want high levels of "tenderness" throughout the relationship, but this drops for men. I wonder what that's all about. I can't see my desires for tenderness ever dropping. :shy: Maybe males prioritize long term tenderness diversity while females prioritize long term tenderness amount?
