If one of the two spouses is sexually and physically strong...
If one of the two spouses is sexually and physically strong, having a fervent and fiery passion and the other one is weak and frigid, most of the matters of their life become upset and unbalanced. There is also a strong probability of corruption and deviation. This lack of balance and proportionality incurs heavy damage and shocks their nerves and spirit. If we wish to explain and illustrate it with more explicitness, it would prolong the book, whereas we have based it upon briefness.
But it must be considered explicitly in its own place. Truly, we must not describe such sexual problems in a naked shape, heedless to modesty, as is customary in some non-Islamic societies, but these must be discussed modesty. Did the Prophet of Islam (s.a.w.a) and other leaders of Islam not describe these problems in a clear-cut and detailed way to teach the people? Can the youth and spouses be overlooked, not given information in the wake of this important matter and essential need”?
Just as we have a specialist for each and every organ of our body, with referral points and places for all the partial or total matters and problems of society, why should there not exist centres and specialists for such affairs of life, family and physical, sexual and spiritual difficulties of the youth and spouses? Is the importance of this problem even less than a tooth for which we have all these specialists, dentists, and well-equipped laboratories?
We have seen a number of examples, which by studying their difficulties and profound and chronic differences in marital life, we reach one sensitive point and that is sexual displeasure and dissatisfaction! Then it is observed that the real and actual cause of all the discomforts is this very point. But they feel shame in expressing it vividly and openly. And in some cases, they do not even know themselves what is harming them.
When we observe that married men and women commit sexual corruption, and develop illicit and illegal relations with strangers and in most cases (though not all), we discover that the reason for these was sexual dissatisfaction and non-fulfilment. One of the main reasons for the deviation of Zuleikha and her inclination towards Yusuf (Joseph) (a.s), was the sexual inability of her husband.
There exist a large number of variant cases, which I have personally observed that I have avoided and overlooked due to various reservations.
