There is a spaceship and on board are some children. The AI on the spaceship is creating/teaching the children. Two of the main characters are boys (maybe 14, 15 or 16) who are in sexual/emotional relationship, although they are not referred to as being gay or homosexual. One of the boys falls in love with one of the girls on the ship and the 'jilted' boy is very upset and fights with the other boy. I'm not sure what the purpose of the ship was (seaching for new planets, maybe). I remember enjoying the book or story and would like to read it again if anyone remembers the name or author.
This is not pornography, even though it might sound like it.
