Aside from my moral objections, I’m shuddering now just imagining how awkward everything would be; before, during, and after.
I’m the direct supervisor of an office full of women.
That would in theory alleviate my “don’t wanna be a creep/lawsuit” concerns, but not my disinterest in casual sex. Or my not-previously-mentioned disinterest in public/group sex, or the fact it’s distinctly possible that all the women here are married - I don’t want to be an adulterer.
I work out of my home, so it’s just me. And I think I’m going to leave it at that.
I work from my home. So does Mr. Athena. We both work for the same company, so we are officially co-workers. I’ll let you guys figure out the rest. 
I’ve got nothing against sex parties, but office sex parties??? With people you work with??? Thats wrong on so many levels.
The entire permanent staff of our organization is myself and two other women. Being all straight females in committed relationships, yeah…it’s just not going to happen.
Hey, if it lets you declare more rooms in your house as work space for tax purposes, all the better! 
YES!
My wife and and also work from home as our own business.
I work at an ad agency, and my office is full of attractive young people (of both sexes) in their 20s and early 30s.
A) They’re all young enough to be my children (or, conversely, I’m old enough to be their father)
B) I’m married (as are many of them)
C) As others have pointed out, such a party would lead to a ridiculously uncomfortable work environment afterwards
Parenthetical: when I first started working in advertising, my manager was an English guy, who had a serious problem with roving eye. He was, in fact, married, though that marriage didn’t last much longer. He had once gone to our agency’s Paris office on business, and came back from that trip very envious of the open affairs that were going on between various staff members in that office.
Big no from me as well. Old, out of shape and lazy. Not to mention the desks in my office are barely fit to work on, let alone THAT kind of work!
Well, I worked at one place that it would be a Big Yes. 
Come to think of it, two places.
No, because after they get a taste of this, I’ll never get any work done.
Well, I’m a university professor, so I’d need to define “office”. Depending on if the definition includes my classroom, my answer is either “Oh, good lord, no” or “Jesus Christ, no!”.
The cute guys in the office are all at least 15 years younger than me, and they’re all (apparently) straight, so I’d just sit in the corner. Never mind.
Another vote for Oh hell no!, for reasons others have cited above.
I think about this from time to time in my biweekly running group, which includes several young, attractive women who, mirabile dictu, seem to like me and enjoy my company. While the perennial eighteen year-old buried in me thinks “Whoah! These hot girls who are way outta my league actually like me!”, the mature 50 year old me knows that the way to maintain this esteem is to obey some iron-clad rules: one, never ask about their personal lives; two, never make any comments about their bodies, save for occasionally on something directly related to running - “Hey, your leg-turnover is good today! Your stride looks efficient!”; and three, the most important - never, ever touch them.
I’m a middle-aged man who greatly enjoys a couple of hours a week spent running with friendly young women who are usually dressed in skimpy shorts and singlets, so it behooves me, I think, to avoid any behavior that comes anywhere close to creepiness. I don’t want to make any of my young friends feel uncomfortable or weird around me; I enjoy their friendship too much for that.
No way. This place is positively stuffed with Alpha-personality lawyers. It’d degenerate into an alcohol-fueled S&M event in 20 minutes. I’m too old to enjoy that.
Hella no!
Well… I did meet my former husband at work, but that’s different. We did have sex, but not parties.
I will confess, if I worked on the set of Animal Kingdom, I would be so tempted.
Is that so? Oh…nevermind. I was thinking Wild Kingdom.
So do I.
When I was much younger, I did work at a place where this went on, and no, it was not any of the restaurants I worked in until I graduated from college.
It was at my first job out of school; there was a small group of pharmacists and technicians who liked to have the wrong kind of good time (and at least two pregnancies resulted; I knew about those because both women had their babies :eek: ) and had any of those parties been raided, I have no doubt that everyone there would have lost their licenses.
