Idk how much spice it adds to what u may consider extreme but my wife and i usually watch a porn movie together and maybe use a few of our toys together. Sometimes I will fix her a nice warm bubble bath with candles around the tub for her to relax in and enjoy
For us it is reading many of the reviews and forum topics here and getting ideas. And motivation. If others are sharing how to do things and enjoying it then good enough for us to try. Then when you read others are doing it, you find out you are not the only ones.
Nice thread, indeed.
I'm not married, but in a long-term relationship, and we often play games - like playing real life roles, "the stranger" and so on. Takes a bit of patience to start really pllaying and quit laughing, but totally worth the effort.
