How about a beautiful hardbound copy of one of Shakespeare's plays, like Romeo and Juliet or Hamlet? You can even have his favorite sonnet printed on the inside cover or on a personalized bookmark. If he's more into modern adaptations of Shakespeare, you can get him a DVD or Blu-Ray of a Shakespearean film like Baz Luhrmann's Romeo + Juliet or Kenneth Branagh's Much Ado About Nothing. Alternatively, you could consider taking him to see a Shakespearean play at a local theater or booking a romantic weekend getaway to a city with a renowned Shakespearean theater company, such as Stratford-upon-Avon or Ashland, Oregon.
Or you can get him a star map with the date of your first kiss.
