Alabama Sodomy Laws

Alabama stealthily introduces its prohibition on consensual sexual acts, including sodomy, by first defining "deviate sexual intercourse" as "Any act of sexual gratification between persons not married to each other involving the sex organs of one person and the mouth or anus of another." Alabama Criminal Code § 13A-6-65 (a)(3) then punishes this deviate sexual intercourse between unmarried couples.

Married couples are further protected from definitions of sexual crimes that apply to unmarried couples by being entirely excluded from the definition of "Sexual Contact". This is defined as "Any touching or the sexual or other intimate parts of a person not married to the actor, done for the purpose of gratifying the sexual desire of either party."

Consensual sodomy is a Class A misdemeanor in Alabama, with a penalty of not more than one year in jail or hard labor for the county and a fine of not more than $2000.00.
