Choosing the second option will be a satisfying answer to the problem of prolonged pre-marital celibacy. Allowing an open and honest relationship committed to in the name of God with best of intentions, will discourage secret or promiscuous sexual behavior which is much more harmful to the moral fabric of a society.
Below I have summarized few reasons, out of many, for the necessity of Temporary Marriage, and the advantages associated with it: As I mentioned, temporary marriage is not necessarily a sexual relation, and it could be for many other reasons. One purpose could be: getting to know each other closely. In the Shia communities it is even widely applied for a virgin girl to enter into such temporary marriage WITH the condition that the marriage is NOT to be consummated.
This is actually for done a boy and girl want to permanently marry, but they don't know much about each other, and to familiarize themselves to each other, they will enter to such contract few months before the official permanent marriage. This period is what is known as "engagement". The engagement for the Shia Muslims means that they have contracted Mut'a marriage.
(There is no other way for engagement in Islam!) In this period the boy regularly visits the girl in the house of the girl's parents and he is considered as a part of their family. They are "Mahram" to each other (i.e., boy can see the girl and her mother without head-cover, as a result of temporary marriage contract). They talk, study, have fun, go to picnic along with their parents, and so on. The boy and girl are husband and wife, but the only thing that they can't do, is to sleep together.
This gives an opportunity to the boy and the girl in order to know each other more closely and to see if they can live together for the rest of their life and if their personal feelings are sort of compatible. Usually if something is found to be wrong, they will break up before the time when they want to permanently marry.
This helps to decrease the rate of divorce in permanent marriage (when the permanent marriage may have been consummated and they may even have children) which is the worst thing in the family life. Another justification about temporary marriage is that, in Islam, the right of divorce has been given to the husband and not the wife. Also according to the Islamic teaching, a girl and a boy can not be with each other before marriage.
