Here is a recent General Conference talk by Prophet Thomas S Monson addressing the Priesthood, specifically the single Priesthood, about how to go about getting married:
Now, I have thought a lot lately about you young men who are of an age to marry but who have not yet felt to do so. I see lovely young ladies who desire to be married and to raise families, and yet their opportunities are limited because so many young men are postponing marriage.
This is not a new situation. Much has been said concerning this matter by past Presidents of the Church. I share with you just one or two examples of their counsel.
Said President Harold B. Lee, “We are not doing our duty as holders of the priesthood when we go beyond the marriageable age and withhold ourselves from an honorable marriage to these lovely women.”
President Gordon B. Hinckley said this: “My heart reaches out to … our single sisters, who long for marriage and cannot seem to find it. … I have far less sympathy for the young men, who under the customs of our society, have the prerogative to take the initiative in these matters but in so many cases fail to do so.”7
I realize there are many reasons why you may be hesitating to take that step of getting married. If you are concerned about providing financially for a wife and family, may I assure you that there is no shame in a couple having to scrimp and save. It is generally during these challenging times that you will grow closer together as you learn to sacrifice and to make difficult decisions. Perhaps you are afraid of making the wrong choice. To this I say that you need to exercise faith. Find someone with whom you can be compatible. Realize that you will not be able to anticipate every challenge which may arise, but be assured that almost anything can be worked out if you are resourceful and if you are committed to making your marriage work.
Perhaps you are having a little too much fun being single, taking extravagant vacations, buying expensive cars and toys, and just generally enjoying the carefree life with your friends. I’ve encountered groups of you running around together, and I admit that I’ve wondered why you aren’t out with the young ladies.
Brethren, there is a point at which it’s time to think seriously about marriage and to seek a companion with whom you want to spend eternity. If you choose wisely and if you are committed to the success of your marriage, there is nothing in this life which will bring you greater happiness.
So, no mention of physical attraction, no mention of love.
Perhaps the Young Men in their Aaronic Priesthood lessons get advice about looking for love in a potential marriage partner:
“We recommend that people marry those who are of the same racial background generally, and of somewhat the same economic and social and educational background (some of those are not an absolute necessity, but preferred), and above all, the same religious background, without question” (“Marriage and Divorce,” in 1976 Devotional Speeches of the Year [Provo: Brigham Young University Press, 1977], p. 144).

So, the appropriate question in all of this official Mormon doctrine and teaching about marriage "where is the love?" (courtesy of The Black Eyed Pea's)
