Been catching up on the other threads, so gutted to only have just found this site. I have some tidbits from the sex industry and sex party scene:
Bercows have an open marriage. Sally has a thing for black guys (this is 100% true as my best friend was one of them and annoyingly won't tell me more than that). A lot of bankers and politicians are into cuckolding scene and 'black mens fan club' adjacent parties.
From second hand floating about escort gossip, friends of friends, so possibly pinch of salt for some of these as with anything:
James Acaster and Phill Jupitus see escorts, as does David Davis (into student roleplay, regular at brothels, this one comes from first-hand reliable source), Viggo Mortensen and Johnny Depp (who are both nasty violent bastards, I'm talking breaking fingers and face-punching), Gordon Ramsay is into coke (surprise surprise) and being topped by trans dommes.
A lot of men see escorts, most are married. Lots of random soap stars and footballers I couldn't tell you the name of
although I did used to work at an agency in Manchester that regularly catered to Man U, including Ronaldo back in the day, although I don't think he shagged anyone, and I was never brought in, don't think I'm their type- no fake tan or tits. A lot of rich self-destructive types including the closeted ones just like to get escorts out to 'party' and are deeply lonely and damaged people.
Oh non sex industry related but I know someone who worked for Karren Brady and unsurprisingly she's a prick
