Unlike the previously mentioned sports, tennis can't be played alone. So, if you've fallen for the sport, why not play it with the person you've fallen for? To add an extra dimension to the fun, bet a week's worth of laundry on the result. If you don't want to play against your partner, jump the net and join him or her for a mixed doubles match with another couple. You can share in the thrill of victory or, at worst, have someone to help smooth over the sting of defeat.
You and your love will be in the same boat, regardless of differing skill levels, with our final couples sport.
