BTW, I am pretty sure pants were not invented until relatively recently in human history. Dresses well preceded pants. Men wore kilts, and other forms, but not pants. Yes, to slouch in without giving anything away.
A woman wearing a bikini in intimate settings for her husband is violating no moral. She may, in fact, be violating morals, if her husband wished her to wear a bikini for him intimately, by her refusal to do so.
So, if a husband truly knew that his wife had total disdain for bikinis, he would be wise enough to never request his wife wear it. I am coming from the basis of always looking to be most loving toward her and not be purely selfish at her expense. So this "refusal" need not be presented over and over, and become a source of repeated conflict.
Chelea's comment I took as coming from a wife's point of view of always wanting/needing to please her husband.
Thanks to Chelsea, as usual, to get matters to deeper levels.
Wanting/needing to please one's husband should not include anything a woman finds demeaning.
