Again, a quote. From here.
We are overwhelmed by sexual images in commercials, art, and pornography, and you might think that the increasing number of images would indicate that we’re moving away from puritanism and towards more positive attitudes towards sex. But in reality, the great mass of those images in all three realms tell us one thing: ‘Sex feels good, but it’s not for you. You’re too fat, too skinny, too old, too poor, your tits or cock aren’t big enough, you don’t stay hard long enough. Sex is for the elite.’
