Another thing we've been conditioned to accept is that clothing is not so much to cover the body, but rather to decorate it. The need to cover those more private areas of our body, for modesty's sake, is no longer a welcome idea in our society. If the weather is fair, we just strip down to the "bare" minimum and have a "good time"...oblivious to the hidden damage we're causing to the hearts and lives of those around us.
The key is that most women (and men) have given up on seeking the Lord to meet their needs in these areas and have been convinced by the world (contrary to God's Word) that there is no escape (compromising your modesty is necessary). Well, you just have to decide in whom you will believe. The Word is clear and the fruit of modesty is well worth any persecution the world can dish out- for us taking a stand on holiness. We need to be taking to heart that "women adorn themselves in modest apparel, with shamefacedness and sobriety..." [1 Timothy 2:9] "As for me and my house, we will serve the Lord." [Joshua 24:15]
This second way of men coping with their wife's accepted immodesty has a huge impact on marital intimacy and this is what most men in our culture choose (or are conditioned from a very young age) to do. This area of a man's heart is a MAJOR part of what enables him to be truly intimate (at the heart level) with his wife. Once a man shuts this area of his heart down (knowingly or unknowingly), intimacy at the heart level is minimal if any.
This has proven very frustrating for so many wives in our culture...the men just seem to be lacking in heartfelt expression for and during intimacy. They are instead flesh focused, absent minded, or at the most they will only interact with her at a mental/emotional level. This is taking away the most important element: for those in the marriage bed to share from the deepest places of their heart (completely and openly) in order to experience and be led by the Spirit into truly fulfilling intimacy together.
The Word presents a much more balanced way for men and women to deal with this need in a husband's heart. Scripture is very clear that the wife belongs to the husband (she is his private property), but the Word also says that the husband belongs to the wife (he is just as much her private property as she is his). Now, as we know from the whole of Scripture, the husband has primary authority over his wife...but the point of the following verse is that the wife also has legitimate rights to be intimately fulfilled by the husband:
[1 Corinthians 7:4] "For the wife does not have [exclusive] authority {and} control over her own body, but the husband [has his rights]; likewise also the husband does not have [exclusive] authority {and} control over his body, but the wife [has her rights]."
Personally I think that's beautiful and I love that God offers this blessing of making us so completely one (body, soul, heart, and spirit) with whom we marry- so that we will belong to each other in the Lord. In the husband's heart especially, if he is naturally sensitive to his wife, an emotional bond forms toward her more intimate and private places of her body. If those areas are exposed to other men, he will feel a deep pain like no other and will be tempted to close this area of his heart (desensitize it)...so that he doesn't have to feel this dull knife cutting at his heart again and again. It actually has very little to do with jealously and everything to do with a man's God given emotional sensitivity to his wife's most cherished places shared during their times of intimacy.
