In case you have not already, check out the film: “Hope Springs”. It has Meryl Streep, Tommy Lee Jones, and Steve Carell. Many marriages likely have this film to thank for in seriously spicing their sexy talk up.
If you want to take it to the next level, Google a TED Talk entitled “Monogamish: The new rules of marriage”. Although it is still about monogamous relationships, it develops fantasizing with your partners about others. That is why I mostly lurk about here. The stuff swingers take for granted are hot fantasies in my book. Yeah, I am monogamous. So posters, please do not spare us the details! We are living vicariously through you here. ;-)
Looking at the menu does not imply you are going to break your diet. You get to make the rules. For example, as they say in swinging, only go as fast as the slowest partner.
In terms of decisions in the heat of passion, my thought is they are the equivalent of promises made under duress. For example, if a client tells seasoned strippers while getting lap dances that he will buy them each a house, I doubt many will run out to hire a mover. Similarly, couples do not usually propose to major commitments during sex. And anything said in the intoxicating heat of passion should be double-checked during a sexually-sober time.
Thanks for the refreshing perspective.
