For me, it's not about having sex or sex acts or multiple partners. It is about 'feeding' different aspects of my personality, occasionally, in diverse ways with sex. It transcends role playing, it's a sexual moment as I'm giving, yielding, engaging and driving my partner(s) into an exquisite moment. To build them up, for the men to enter me in a pure moment that thrills or kissing a woman with tongues plunging deeply. I love it when someone I may have just met can surrender to me and I to them. Then, once we're done that it's perfectly alright to go to the next partner and, who knows, have that same person again later that night (or not). Or, if it's simply to play with another couple, have the sex with the husband be so great that the wife thanks me. Then, of course, there's the knowledge of my husband having another girl, whether it be a wife or innocent bystander, knowing she just might be asking herself if watching me fuck means my husband must be amazing (he is).
