You have entered a new world, one in which you must react in a slightly different manner. Jealousy is dead. In it's place you have an opportunity to share someting unique. Something that still remains exclusive to you despite the fact that it may include other individuals. in your communications with each other, you support each other. ensuring that each achieves satisfation not only for yourself, but for your SO. Did you enjoy hearing her cries of ecstasy as she was entered? Wasn't it delightful to see the look of pleasure on his face as she devoured him?
