Sorry, but you have turned an ant hill into a very expensive time-wasting volcano, single-handedly, just for you.
The upshot is that now over a bed sheet and a kettle (latest demand), your event has turned into a 'federal' case requiring a LOT of time on everyone's part that you could have used to either improve your listing or approach and Airbnb helping other hosts. To me, this is a also a classic case of a host NOT handling an issue, as common as 'too many guest', on the spot, in their place, in the first place. Airbnb is a booking agency, not your business partner nor guardian angel.
Your case is just not resonating with them, by more than one case manager at more than one level. In actuality, they are quite reasonable (excepting the occasional fluky employee), if approached logically. Your whole Viagra/'sex drug' hangup comes across a bit illogical.
The point is - take more personal responsibility over your place next time, which will either eliminate or lessen such hassles in the future. Also look at issues pragmatically, a sheet plus a electric kettle (they are cheap, but power hogs and oftentime will trip breakers) surely wasn't worth this whole exercise; many experienced hosts would have moved on long ago, but made adjustments accordingly.
