It shouldn't come as a shock to anyone to hear that relationships now days are almost always founded on sexual attraction as an important element especially in the early stages. It also should not come as a shock to hear that marriage has been turned into a risky proposition with high risks and few rewards rather than a binding contract that being in was required for social acceptance.
There will always be a large portion of men that women have no sexual desire towards but under a society that restricts women's independence and makes marriage serve a positive purpose then marriages of convenience will arise, sure a woman might not be sexually attracted to a man, but better to settle and live a fulfilling life than to remain single and be treated worse for it.
