Make a list of at least 6 fun things to do when making love. They can be new things or just your favorite things like get a back rub, kiss me where I pick, shave her legs, do a strip tease, etc.
There are many variations on how to do this.
You can write each one on a 3 x 5 card or a small piece of paper. Then before going to your bedroom (or where ever) give your lover a dice and have them roll a dice to determine which item to try. If you have the little bottles that contacts come in, you can have a very small note folded up and placed in the bottle and these can then be closed and allowed to float in a bubble bath. You can put 5 or 6 of them in and take one out after a while to see what your fate is.
Sometimes we just use a dice to pick what clothes we will wear during the evening. It might be a choice between a mini skirt, a teddy, or jeans and a tee shirt with no bra. You can also add in a fantasy and then if you roll the same number twice, you get something really special. But be sure you both agree to do the fantasy. Never do anything that you both will not agree to.
The best part, each time you can change the cards or notes and you can add another dice to add even more choices. The possibilities are endless but fun.
