Men and boys are harder to make quilts for because there is less fabric choices out there in things men traditionally are interested in. Think wildlife, jungle animals, nature, space, sports...try to find what he is interested in and search for at least one fabric with that topic. My husband has an interest in steam engines, motorcycles, and airplanes. I did a 6in square of the topic fabric and alternated them with a 6in pinwheel block of coordinated fabrics.
