It doesn't matter what birthday gift you give to your boyfriend. The most important thing is to make him feel that you care about him. The two most important points of a gift are that he likes it and he is touched. As long as the gift includes these two points, any birthday gift for a boyfriend born in the Year of the Pig is good.
