Is this common at FKK clubs, even when they don't go AO/Raw/Bareback no CIP ?
Also, at the places that specialize in AO/ Bareback, is CIP the norm?
And if CIP is allowed, and they do Greek, is CIA usual (since that's the big HIV portal that makes Gays so hazardous)

NQNS is pretty rare.  CIM is pretty common, usually for upsell at non AO FKKs.

At AO clubs, CIP is common, with exceptions.  Some ladies will ask you to pull out first.  Also, not all girls at AO clubs allow AO.  Often time, you need to ask discretely on the couch.

I can't answer the CIA question, not my thing.  The only two girls I know of at AO clubs that allow Greek don't do AO at all.

Good luck!
