If you want to diverse your sexual life somehow, you can share this idea with your partner.
If you intimate relations became boring, you should invent something to increase the adrenalin in the blood. Perhaps, pillow fights will help you.

Imagine- your wife is taking a shower. You are waiting for her in the bedroom, but when she comes and starts to tease her husband, you pretend sleeping. She, keeping her mind, takes the pillow and strikes you. Now it is your turn not to lose the game

Such games are quite normal and usual in Japan. One man even described 8 040 ways and rules of pillow fight! They all are intended for strengthening emotional relations of the couple.

I think the idea is pretty funny, and what do YOU think?
