When selecting a birthday gift for your boyfriend, it's important to consider his interests and personality. Think about the things he loves or hobbies he enjoys. For example, if he's into sports, you could get him tickets to a game or sports gear related to his favorite team. If he's a tech enthusiast, a new gadget or accessory might be a great choice. Personalized gifts like a custom photo album or a heartfelt letter can also make the occasion special. Remember, the key is to show that you've put thought into his gift, and it aligns with his tastes and preferences.
