Sex is a part of marriage and is the duty of both to make as fulfilling as possible. Work is often a joy if you are working in a suitable field, sex is often a joy if your doing it with a suitable spouse. Work is often a drudgery because of the curse, sex is often a drudgery (for men and women) because of the withholding of the total person in naked, uninhibited oneness.
If a wife tells me she feels like a sex doll, I am pretty sure she is dead in bed and not fully participating. No doubt her husband is infuriated with her comatose coitus. Why does she feel entitled to such sandbagging in bed? Maybe because she feeeels entitled to be the princess, not the helpmeet to her man, not submissive to his desires and she has defrauded him by reclaiming the authority over her body that vowed to give to her husband. Our Bodies Ourselves was another important book in the feminist assault on the marriage. It seems from your posts that its premise may have been incorporated into your philosophy of marriage. The apostle Paul makes no exception for your feeelings, only for an agreed time of fasting and prayer.
Ok, guys, there you have it, apparently you are always entitled to it. Dave, the Catholic marriage is to build a family, and the husband is supposed to lay down his life for his wife, so who exactly is submitting to who?
