Well, I am not Mormon, but I can answer your question in regards to the bible. There's a great section in the bible written by the apostle Paul --thoughts on both marriage and singleness. (the capital words are mine). From 1 Corinthians 7, in the MSG: A GIFT "...Sometimes I wish everyone were single like me - a simpler life in many ways! But celibacy is not for everyone any more than marriage is. God gives the gift of the single life to some, the gift of the married life to others. GET MARRIED IF YOU CAN'T MANAGE YOUR DESIRES/EMOTIONS "I do, though, tell the unmarried and widows that singleness might well be the best thing for them, as it has been for me. But if they can't manage their desires and emotions, they should by all means go ahead and get married. The difficulties of marriage are preferable by far to a sexually tortured life as a single. ADDITIONAL STRESS "...There's certainly no sin in getting married, whether you're a virgin or not. All I am saying is that when you marry, you take on additional stress in an already stressful time, and I want to spare you if possible. KEEP IT SIMPLE "I do want to point out, friends, that time is of the essence. There is no time to waste, so don't complicate your lives unnecessarily. Keep it simple - in marriage, grief, joy, whatever. Even in ordinary things - your daily routines of shopping, and so on. Deal as sparingly as possible with the things the world thrusts on you. This world as you see it is on its way out. I want you to live as free of complications as possible. TIME WITH JESUS FREE OF DISTRACTIONS "When you're unmarried, you're free to concentrate on simply pleasing the Master. Marriage involves you in all the nuts and bolts of domestic life and in wanting to please your spouse, leading to so many more demands on your attention. The time and energy that married people spend on caring for and nurturing each other, the unmarried can spend in becoming whole and holy instruments of God. I'm trying to be helpful and make it as easy as possible for you, not make things harder. All I want is for you to be able to develop a way of life in which you can spend plenty of time together with the Master without a lot of distractions. DECIDING "If a man has a woman friend to whom he is loyal but never intended to marry, having decided to serve God as a 'single,' and then changes his mind, deciding he should marry her, he should go ahead and marry. It's no sin; it's not even a 'step down' from celibacy, as some say. On the other hand, if a man is comfortable in his decision for a single life in service to God and it's entirely his own conviction and not imposed on him by others, he ought to stick with it. SPIRITUALLY AND MORALLY RIGHT "Marriage is spiritually and morally right and not inferior to singleness in any way, although as I indicated earlier, because of the times we live in, I do have pastoral reasons for encouraging singleness." GOD DEFINES YOUR LIFE "Don't be wishing you were someplace else or with someone else. Where you are right now is God's place for you. Live and obey and love and believe right there. God, not your marital status, defines your life....Friends, stay where you were called to be. God is there. Hold the high ground with him at your side."

it may not be strictly essential, we are however commanded to marry if at all possible heavenly father understands if we are not able and will judge us accordingly.

"Neither is the man without the woman, nor the woman without the man, in the Lord"

What's god eternal plan? Is that anything like Universal Healthcare? Do we get any free beer with it?

Well, since it depends of free will, it's can't be essential. Not that I believe in any of this.
