Hmm... how did my great great grandmother manage to get married at 16 and live with her husband for many decades until he died, leaving her pregnant with their last child of a great many children (that last child died in infancy while the older ones survived into adulthood)?

I always ask myself this question when I see theories about adolescent sexuality being an artificial result of marketing ploys.

On a more individualized note, the age of puberty varies and the age when you become interested in sexual things varies a lot, too, and you are well within the norm with nothing to worry about. But depression should be treated, not in an effort to increase the desire but in order to have the much needed energy for life, schoolwork, etc.

If that is any reassurance, I did not get into serious drive until much older than you are now, but in 5he end my level of desire is above average.
