My brother, if thy wife truly knows thy heart and thy sexual desires, thou shouldst not have to tell her such a thing. Now if thy wife opposes the consumption of thy genitals orally, then that be'st another story.
Otherwise, take thy wife and speakest to her of thy desires to be pleased orally. If she loves thee as she hath vowed, then she wouldst take the matter to heart and seek to please ye. But take care not to force thy wife into a thing of which she is not comfortable. May God add a blessing to thy marriage.
My slim cinnamon sister, whereforth hath thou been taught such lies? The Bible speaketh not on such matters because God hath blessed the union of a husband and wife and if thou wishest to be pleased orally, God hath not forbid.
Sodomy in its natural, original meaning simply means unnatural sex between man and man. Today, we have added onto the definition to sometimes include oral sex but that be'st not biblical my sister. The only forbidden things sexually between a husband and wife are : Adultery, Incest, Fornication, Anal(my opinion), Homosexuality(Sodomy), Lesbianism, Orgies, Sexual toys (dildos, vibrators, flesh lights, etc) & Prostitution.
