Even if the law is on the books in some states, it cannot be enforced due to the ruling in Lawrence v. Texas (https://en.wikipedia.org/wiki/Lawrence_v._Texas). Also, sodomy is not limited to gay men (https://en.wikipedia.org/wiki/Sodomy).

Certainly there are laws based on morality, but it's absurd to claim that all laws are. Laws regarding the legal status of married people also help standardize common relationships. Can you imagine having to precisely define your non-married long-term relationship every time you fill out a form at the doctor's office or bank? The legal concept of marriage exists largely to codify the shared responsibility of each spouse when it comes to contracts, financial obligations, child care, etc.
