Fr. John Breck in his book The Sacred Gift of Life: Orthodox Christianity and Bioethics makes this statement about procreation. He also says that the univite nature of marital relations is honorable, but is a blessed corollary to the more fundamental purpose of procreation. I've always thought that he was right. I'll read up more about the topic though. Thanks.
Well, I guess I must conceede this argument, all I can cite in support is Paul, Basil, Nyssa, and Chrysostom...I don't have anything to put up against a Fr. John Breck.
In all seriousness, yes reproduction was the original point of sex, billions of years of biological evolution bear witness to this. But we also observe amongst animals of higher intelligence (including homo sapiens) an enjoying of the act for itself, for pleasure independent of reproduction. And amongst the most intelligent of animals (i.e. homo sapiens), the one species that actually understands the mechanisms of sex (though granted, we just started to have a good grasp on it over the last 200 years, but long before that we had some pretty good hypothesis) the purpose of pleasure has become the primary concern. Perhaps, on the grand scale, perceptions of sex are related to overall intelligence; in which case, pleasure should be the most noble asperation for sex, since it is only the most intelligent species that exploit it for this pleasure and homo sapiens that enjoy this pleasure while having also learned how to deal with the often less pleasurable (depending on circumstances) 'side effect' of reproduction.
