3. Touch
In the beginning of a relationship you can't keep your hands off each other. It's time to recapture that. That doesn't mean you have to go makeout in an elevator or the back of a cab (though go for it if the opportunity presents itself!) but you can do it in subtler ways.

Hold hands again while walking. Give each other long kisses as your hellos and goodbyes. Run your hands down their arm while you're grocery shopping. Wrap your arms around their waist while you're waiting in line for something. We crave contact, and you will feel more connected and in love if you're constantly touching one another.
