Well, it depends on what he likes! If he's into sports, you could get him a jersey or a new pair of sneakers. If he's more of a techy guy, you could get him the latest gadget. If he's into music, you could get him concert tickets or a new record. If he's a foodie, you could take him out to a nice dinner. Or, you could always get him a classic romantic gift like jewelry or flowers! Just make sure you pick something that shows you know and appreciate him.
