The New Functionalism

According to Iowa Republican representative Steve King, sex has two purposes: procreation and recreation. He's using this to argue that the new Medicare prescription drug coverage should not cover ED treatments, calling them "sex enhancing drugs." Such narrow thinking about the function of sex is to be expected from someone who hasn't fully grapsed that it is 2005, not 1955, let alone how some religions view sex. Further, it sounds like the Congressman is confusing Viagra with lotions or other paraphernalia. Would someone please explain to him the difference between a legitimate medical condition and a need to impress one's partner?
