One of the reasons is that my wife experiences pain during intercourse. This is something we still have to work out, but it was also getting in the way of other types of sexual activity. Even though I am happy to play in other ways, she had no interest just in case it developed into intercourse. Her sex drive was zero, and we fell into a long term sexless pattern where we never tried because she didn't want to the disappointment of "failure". She had actually given up on the idea of having a fulfilling sex life and used to joke about becoming a nun.
In an attempt to turn this around, I did some research and found this game. She was open to the idea as she knew something had to change, but was very skeptical. Several attempts to schedule an evening were delayed until last night we finally had a go. As I gathered the toys together, she became extremely nervous and I was sure she might pull out. (A tip for others in a similar situation - leave the toys discretely accessible somewhere, don't put them all in a pile on the coffee table!)
Setting up the game initially was uncomfortable. She was unclear what the actual objective of the game was, as I made it clear that the basic game did not include intercourse. She didn't really understand about setting the maximum passion level, and fear of the unknown made her want to set it to "warm". I explained that it probably made sense to set it to the maximum and we could always dial it back manually or stop if either of us got uncomfortable. We also set the game speed to "Slow".
After several drinks (this really helped!) and the gentle early rounds, she was clearly having fun. Although some of the talking actions were initially disconcerting, they really worked well at increasing the passion level and making us comfortable just talking about things like that again. As the actions got bolder, I was amazed at the gusto she put in, and as our clothes started to come off we were both having a great time.
We ended up playing for more than three hours, spending quite some time at the Nuclear level. It was the most fun either of us had had for years - I never would have thought such a release of inhibitions would be possible in one session! I had always been curious about playing with toys like food, but wouldn't have suggested it ... but when it's an instruction from "the game", who are we to disobey it?!

I credit this game with rescuing our sex life, and possibly making it even stronger than the early passionate days! I look forward to playing it again and again.
