It isn't the planning or the execution of the sex party you should sweat. It's handwriting all those damn "thank you" notes afterward that'll get to you. There's only so many times you can use the adjectives "mind-blowing", "rock-hard", "cum-soaked", "ass-stretching", not to mention others, before you feel you are just repeating yourself. And really, don't your guests deserve unique and cherishable thank-you's, not something that could have just as easily have been xeroxed?
Yeah, I know -no help whatsoever. But when someone asks about hosting a sex party, Judith Martin pops into my head. Some day, I'll have to write a sex-etiquette manual. Problem is, I don't think I could treat the subject matter with the seriousness it deserves.
