There was a book I read in junior high and I need help finding it?

I will add as much as I can remember about it, the people in the world did not choose their jobs, it was chosen for them, and the main character was chosen to be a storyteller or adviser or something, girls did not choose when to have kids that was another job to be a mother and then the kids were given to parents, the clothes everyone had were gray or black I think, when the main character had a wet dream when he hit puberty where he was at the place he volunteers and he was in a bath area and told a girl who was his friend to take off her clothes and he told his parents and they gave him a pill and he did not have anymore thoughts like that, the previous storyteller/adviser starts training the main character by giving him visions by touching his back I think, he gives him visions of war and of love I think, and at the end he escapes this dreary world and stumbles upon a christmas scene I think, if you need anymore info ask.
