Bring her flowers/chocolates, with a poem or a note telling her how beautiful she is and how much you love and care for her or a breakfast in bed with a note/poem. Spend sometime talking with her and tell her that you have a surprise for her later on. Pick out of special place or restaurant or maybe even a trip of some sort, make it fun by giving her hints and pictures via text message; make it so it isn't even possible for her to guess, but keeping her interested and getting her pumped. After the event, take her home and give her a nice long massage with oil, and love each part of her body, making the entire time about her. Care for her before yourself. After all the fun has ended, give her gift like a teddy bear or something (maybe something that is her favorite color or animal or activity) with a little song if you can sing/brave enough or another note / mix of songs or the lyrics to your favorite song and snuggle with her for the rest of the night. Awaking her with a breakfast in bed the next morning.
