Literally when I read this what it comes off as is - woman uses a crowd and an audience to manipulate a guy who isn't comfortable having sex in public, to do so, and then when he's not happy afterwards, blames him for being not as sexually liberated as her and thus makes assumptions about all vanilla people not being open minded.

Imagine if a man had just decided to start fucking a vanilla woman at a fetish party in public, and people were watching and cheering, and explicit consent wasn't obtained beforehand, we would all agree that would be fucked up right? So why is it different when it's a man??

Just because he didn't say no doesn't mean it was consent. It's like when people propose in front of crowds of people, they feel pressured to say yes because the crowd will boo if they don't, making someone who hasn't beforehand said they want to have sex in public, have sex in public, is making it very hard for them to feel like they can say no.
