5. Get sweaty
Dance studios are full of couples. Join them and develop and improve your dancing skills with your spouse. It is a very romantic activity that will entertain both of you.
6. Classic: Simple and Sweet
The best ideas are usually very simple and easy to do. Writing a message and leaving a red kiss on it works just fine! Preparing a meal with candles on the table and a bottle of good red wine is great, too. Feel free to use your own creativity and express yourself the way you feel it. Listen to your heart and follow your intuition.
