Many other social problems such as drug abuse and adultery and drug abuse are also not motivated by physical pleasure. People become drug abusers because of poor self-esteem and poor judgement, not physical pleasure. Anyone with even the most vague knowledge of drugs will know that while they may provide a short-term "hit", they eventually burn out the pleasure centres in your brain, thus robbing you of all life's physical pleasures. In the long term, drugs reduce physical pleasure. And what of adultery? Adultery is motivated by the excitement of its illicit nature and perhaps by dissatisfaction with one's marriage. However, to put it bluntly, another woman's vagina will not feel a whole lot different than your wife's vagina. To put it even more bluntly, the vagina of the most beautiful woman in the world won't feel any better than the vagina of an unattractive woman. Men stray for myriad psychological reasons, none of which have anything to do with physical pleasure. In the end, adultery is a relationship problem, not a hedonist problem.
So let me get this straight, rape is not pleasurable, but rapists rape people "to get off?" And adultery isn't really pleasurable or hedonistic? Then "pleasure" is redesignated as just "physical pleasure."
But that's silly, because neither hedonism nor religious doctrines of morality make any distinction between physical or other types of pleasure.
