Nothing this year. I always just liked small surprises with no expectations. I haven't ever wanted anything specific on a Valentine's Day, or even expect to get anything, but the best things I have gotten were just little objects/gestures that reminded me of the relationship.
Years ago I got roses. At first I thought it was just cute, since traditionally men buy roses for girlfriends. My girlfriend at the time said she wasn't sure what to do, but knew I liked roses (I have several rose tattoos and mentioned red roses are my favorite flower.) That she made the association was the best part of the gift.
