I might have this wrong in my interpretation but I was a server at a tea party in Silicon Valley in the late 70's. Only the 3 servers (all male) were nude and the ladies were all very nicely dressed in stockings and heels. All of the women were over 30 and I was the oldest at male at 26. There was supposed to be no sexual touching and as I remember one of the fellows was asked to leave after he became erect. Not his fault as he had been asked to give a woman a foot massage and the whole process got him a bit too involved. The party lasted 2 hours and Im sure if the age issue had not bothered me I could have hooked-up (a term not in use then).]
I assume it was some type of reverse power trip as I was there as a favor to a female friend that I was not involved with. Did not see the erotic potential of the event at the time but then I was never the sharpest knife in the drawer to begin with. These days I would gladly do the same again but now I'm too old and saggy to provide any visual or other entertainment to a similar crowd. Another case of youth wasted on the young.
