How about getting him a personalized leather horse riding whip with his initials on it? You could also get him a private horse riding lesson with a professional equestrian instructor, or a guided horseback trail ride in a scenic location. Another idea is to gift him tickets to a horse racing event or polo match. If you're looking for something more permanent, you could consider getting him a piece of equestrian art or a decorative horseshoe to display in your home.
Or you can get him a star map with the date of your first kiss.
