Or decide that you don’t want to marry at all since marriage is just a religious institution devised to prop up a corrupt caste system, particularly among helots where it is synonymous with breeding and thus requires the opposite sex.

“We the People of …, in Order to form a more perfect Nation, establish Justice, insure domestic Tranquility, provide for the common defence, promote the general Welfare, and secure the Blessings of sexual liberation and orgies for all to ourselves and our Posterity, do ordain and establish this Constitution.”

On a more serious note of any nation was ever in need of a good deal of sexual liberation it would be the Hegemony.
You don’t need a “noble” for that “marry” a helot or yeoman or a furry, the class system is nothing but nonsense anyway.
Or just decree yourself Monarch and make new nobles if that is such a big deal.
