There is a problem in martial, and other man-woman relationships, where the sex drive of the man exceeds the sex drive of the woman.
On some forums, I have read posts where some women have taken the approach that their husband's higher level of a sex drive, was an addiction. The problem with the addiction view, is that the solution to work out the difference in sex drives, is not considered, because the difference is entirely the fault of the addicted spouse.
The ordinarily workable solution is for the Husband and Wife to work out accommodations, for the husband to achieve reasonable satiation, within the boundaries of the marriage.
The problem with the sex addiction or p 0 r n addiction model or approach, to the difference, is that the addiction model places the entire fault for the difference in sex drives, upon the spouse with the higher sex drive.
This means that the spouse with the lower sex drive, has no obligation to try to work out mutually satisfactory, loving accommodations for the difference in sex drives.
Certainly there are some spouses who have gone overboard to the extent that they could probably use some help, themselves.
But more often, I have seen a spouse on a Discussion Forum, in a marriage with a difference in sex drives, to take the approach that the other spouse is addicted, rather than trying to find mutually accommodating, loving solutions to the difference.
Sometimes there is a difference in the desired timing of sex. Some like the morning, some like the evening.
Sometimes there is a difference in styles, positions and methods of stimulation.
Sometimes there are sequences of self-stimulation, that are important for satiation of a spouse. Visual imaging can enhance satiation for many men.
