Make the Most of Valentine's Day

11. Do something thrilling. Watch a sci-fi or monster movie, and cuddle with your sweetheart during it and afterward. A few thrills increase your adrenaline, which ups other hormones as well. Pick a classic movie — forgo the ones with too much violence or gore — and hold each other tight. Then go upstairs and burn off that adrenaline.

12. Get a joint massage. It's very romantic to get a massage lying side by side by two massage therapists. Find a place, if you can, that has private or co-ed steam or sauna rooms to be in before or after. If that is out of your price range, see if the same treatment is available at a massage school in your area. Can't find a parallel massage experience? Then do individual ones at the same time and take a walk afterward, enjoying your blissful state together.

13. Go ballroom dancing. You might be surprised how romantic and fun it is to twirl around with your partner on a dance floor. Dancing together can be very seductive. Take a lesson and, if you enjoy it, keep the passion flowing with a whole series of lessons. If ballroom isn't your thing, try line dancing or the Texas Two-Step.

14. Rent a cabin in a small  town or swap your place for another. Getaway places in tourist destinations are expensive, but out of the way places without tourist facilities can be surprisingly cheap. Look for places on the Internet, and even consider a house swap so that you both can have a great place without any expense at all. Make sure you use an Internet site that does due diligence on the people who offer up their places — and do some investigation yourself. While there are always exceptions, a carefully researched swap or an off the grid cabin can make for a very romantic Valentine's Day indeed.

15. Get artistic. Just about every large city (and many small ones) has a store that offers you the chance to take a plain piece of pottery, paint it, fire it and admire it. Sure, it's usually kids there — but aren't we all kids at heart? Another way to express your love and inner artist is to try a free online expressive drawing class. Your work of art to each other may not land in the Louvre — but it will be a fun experience and a memorable gift.
