<p>Is marriage compulsory? I don't not think so. I am yet to see any law which says it's citizens must marry. Even the holy book never made marriage compulsory but only admonished.</p><p>It is undeniable that there are so many benefits of being married but still that doesn't make it compulsory. It is more it is expedient but not a law. If you marry, well, two good heads are better than one then there is procreation and legal satisfaction of sexual urges.</p><p>It is important to marry and procreate so the human race can continue but it is not binding on anyone. If it is a law in some countries, I would love to read about it. </p>
