Food. Guys of all ages have to eat. But what kind of food does he like? Does he like spicy sauces? Get him a gift assortment of hot sauces. What about a gift card to his favorite restaurant? What about a back rub? Foot massage? You can give him one or get him a gift card for one.
Does he like to drink? I've seen gift assortments of various types of daquiri mixes. Does he like coffee? I've also seen gift assortments of coffee syrups.
Does he like funny gifts? Search Amazon.com for "white elephant" gifts. I saw an Easter Island kleenex box where the kleenex comes out if its nose.
I have a long time interest in psychology, specializing in relationship dynamics for 30 years.
