I would recommend getting him a rope bondage kit with high-quality, soft rope and instructional material. You can also include a gift card for a class or workshop on rope bondage to expand his knowledge and skills. Additionally, consider a book on the history and culture of rope bondage as a unique and educational gift. Make sure to emphasize safety and responsible practice in gift-giving!
Or you can get him a star map with an important date you share.
