My husband and I just did this (his idea) and we had SO much fun.
Go here and print off the coupons for 43 kisses and gather some candies (m&ms, Skittles, mints, licorice, Hershey's Kisses), and something to drink (we had ice water and the ice came in handy).
Set the mood! Turn on some music (may I suggest the Rob Pattinson station or Iron and Wine station on Pandora ?), make a comfy spot on the floor, turn off the lights, and light the fire (or some candles).
Take turns drawing different kisses out of a hat. Kiss your spouse as indicated and then discuss what you liked/didn't like (although kissing is like pizza, even when it's bad, it's still pretty dang good!).
We laughed, we made up our own kisses, we spent some quality time together. Ahhhhhh.
