Sex is a surefire way to get happy any day of the week, but if you really want to kick up the happiness factor, try some new sexual positions. After all, having sex the same way every time can make even sex boring! Experiment imaginatively before, during, and after sex. You can get in plenty of stretches and a decent cardio work- out as well, not to mention get all of those pleasurable endorphins flowing. If you can’t dream up any new ways to turn on, tantalize, or titillate your partner, try reading the Kama Sutra or visit your local bookstore or Amazon.com for books that can provide some insight. Bring the heat back into your relationship with some imaginative sex.
