I'll also propose the limit of evolution based on this discussion, since the most outspoken champions of evolution are those most vocally supporting sex for pleasure only. The propagation of superior genes will not occur if this is the case, since obviously the less educated will reproduce like rabbits, while the more educated will use contraception and have less offspring. It is clear from the theory of evolution that the purpose of sex is reproduction and that pleasure is a side effect, not the other way around. Thus, for the above-quoted statement to be true, the theory of evolution must be false.
You have it totally reversed. The reason sex is pleasurable, is an evolutionary adaptation meant to encourage people to do it, thus reproducing.
However, people who argue that contraception defeats that purpose in more highly technological societies, also neglect to realize that evolution is not about quantity. Not only that, but genetic evolution is now not the most important measure of natural selection, since it is far to slow to keep up with the development of civilization.
Before we continue this discussion, may I suggest that you read up on
