My Boyfriend's an Alien

Can an alien with no knowledge of humans or concept of sex find lasting love with a human man?
Zak, an alien from the planet Trimmeron, is a member of a race of beings who transform into other species during their years of puberty. It’s customary for the youngsters to be fostered to the worlds native to their new forms, to study and learn about the races who will play an important part in their lives.
When Zak turns into a human it comes as a surprise to everyone, for only one other before him has ever done so. Nevertheless he is sent to Earth, a world he views as primitive and barbaric. He arrives with a chip on his shoulder and attitude to spare. He does not believe anyone on Earth can have anything to teach him.
When Zak meets college student Sam he soon discovers he has a lot to learn, not only about humans, but also about himself.
Trapped on an unfamiliar world and in a strange body that seems to have a mind of its own, Zak has no idea what is happening to him, only that Sam seems to be the key to the strange afflictions he is suffering from.
But can an alien find love with a human being?
