As long as there are people who are willing to fulfill a duty and perform sexual service by accommodating those who feel entitled to have sex by virtue of the fact that they have committed to be in a relationship, those who feel entitled to sexual service will have no interest the kind of sexual bond that results in psychologically spiritual sexual liberation, which is not for everybody.
It changes your body so that sexual energy is automatically converted to spiritual energy and liberates you from sexual desire completely. People who attain this would rather run their sexual energy internally and let it fuel the newly found enlightened state within than have sex. They can still have sex if they want to have children, or to enlighten someone else's candle. But that is about the only reason people have sex, once they have attained sexual enlightenment.
Women who accept the responsibility of having dutiful sex are enablers of the hungry ghost and demon of lust, sexual addiction, in the same manner that a codependent enables and alcoholic to drink.
