What should I get my boyfriend?

ok well my boyfriend knows exactly what to get me for my boyfriend but im not sure what to get him I know all of his interests and I've had some ideas but he doesnt want me to get him anything and wont let me buy things I want to buy him so I need some help to get him an excellent gift so please please help me figure something out im gettin desperate here..

does he like spiderman or transformers? you can look on ebay to get original vintage toys still in the box. its something out of the ordinary. Or you can get a personalized gift like make him a scrapbook of your relationship, or take it further and get a gift certificate for you two to get your portraits taken and then give him a nice frame that they can go in.
