1 Corinthians 7:3
Let the husband render unto the wife due benevolence: and likewise also the wife unto the husband.
Note 5 at 1Co 7:3: The literal meaning of the Greek word "EUNOIA," which was translated "benevolence" in this verse, is "kindness; euphemistically, conjugal duty" (Strong's Concordance). The American Heritage Dictionary defines "conjugal" as "of or relating to marriage or the marital relationship." This verse is speaking of not withholding the sexual relationship from one's mate. This point is expounded on in 1Co 7:4-5. Special attention needs to be paid to the word "due" here. There are sexual actions that are not normal, and God never expects a marriage partner to perform ungodly sexual acts. No one can honestly try to use this scripture to demand any type of perverted act from his or her mate.
