Yes as a matter of fact we had the big "C" talk today in Priesthood as presented by one of our amazing elder's quorum teachers Alex. It was not your standard chastity talk as it was more focused on the difference between love and lust and how they relate respectively to chastity and fornication/adultry.
I feel that I have come to appreciate some of the nuances of this through different relationships and was quite intrigued when our Bishop indicated that a major difference between love and lust was that love has an appreciation of the person as a whole, a healthy view about their strengths and weaknesses and how those compare with the other party involved. Lust, however, focuses on one item to objectify the person into a thing. There is no whole to enjoy because the person becomes just their; hair, or their eyes, or their ankles, or whatever it is that pleases you. It is a selfish motive and does not help you or the other person grow.
I also found out that the cure for lust is to know what love is.
After you taste what love is and can be then you never want to indulge in lust because it is empty and tastelesss
