Push your Valentine's date to the weekend and book a reservation for lunch at an upscale restaurant. Tasting menus are often much more affordable and the atmosphere less stuffy during the day. Plus, you won't have to worry about being too full when it comes time to hop in bed together.
Be romantic and nostalgic at the same time by reliving your first date together on Valentine's Day. Go back to the low-key pizza joint where you first met, or rent the movie you saw in theaters. With luck, the butterflies you felt that night will return.
Embrace your inner nerd and head to a museum during the week of Valentine's Day. Many museums are open one night of the week, and some even put on Valentine's Day events. For example, the California Academy of Sciences in San Francisco hosts an "Animal Attraction" event, which includes lessons on the science of sex and live music.
