What should i buy my boyfriend for Valentines Day?

Last Valentines day he gave me a dozen real roses, a balloon, a red gift bag with: a stuffed dog, 2 bears that hug each other, 4 fake roses, a heart shaped box filled with hershey kisses & a chocolate rose with little heart shaped chocolates. I wasn't really expecting anything from him and I never bought him anything. I feel bad and I want to make up for it because I know this years Valentines Day he's going to buy me more stuff. What should I buy him ?! Haha any ideas. Im not sure what to give him, because what do you give a boy on Valentines Day ?
