The selfishness and destructiveness of the behaviour is very closely related to the norms it violates. Homosexuality was (and is) destructive to families in communities where it considered abhorent. Premarital sex too. In fact, the ban on premarital sex and the ban aon adultery are closely related. People have a hard time suppressing their sexual urges. But, many sexual urges we once considered immoral & destructive are now seen differently.
