Girl on the Net wrote a brilliant blog piece about this a few months ago regarding sex party clubs like Killing Kittens and their attractiveness criteria.
i found out about a womans club called Skirt Club through an article in Grazia and i thought "i bet its another one with this" criteria" And sure enough after a quick google i found an old article from 2 years ago with the usual spiel. Even better on Skirt Clubs twitter bio its got #feminism. Yep Because its feminist to rate a womans attractiveness now apparently.
But every person has a different idea of what is sexy . I tend to prefer older men. And quite frankly had my best sex with an older guy who was overweight.
These clubs sound very elitist and it just makes the sex sound mechanical because its basically saying "come join our club where you can have as much sex as you want with ppl who the media define as attractive"
