@maxdancona,
If what you are saying is true then there should be no problem with adultery. Indeed, it should be encouraged because it is better to have sex with a young woman with nice curves instead of an old woman or a fat woman. In other words, there is no reason to develop a close personal relationship with another person. Your perspective is abhorrent to some (many) women.
No matter the means of marriage (arranged, through dating, etc.) a man and woman lose a lot if they don't relish the relationship they have with each other. It is a shame.
You are an example of why marriage is on a death bed. Dating has been turned into legal prostitution. Women want to be in a world where men are not necessary. Some in society want to pretend that there is no male and female. Our society is incredibly messed up.
