It was the joke that blew up in Natasha Spencer's face during Wednesday night's explosive dinner party.
The remark set off a dramatic turn of events as Michael took umbrage at the comment and told Mikey – who stormed off, angry, devastated and clearly embarrassed.
After watching the moment play out, fans took to social media in droves to call out Natasha for "sex-shaming" Mikey.
"Not cool to reveal what happened in a sexual experience especially on TV. Natasha- not a good move," wrote one viewer, while another added: "Natasha there's a difference between a personal joke, and making someone a joke..."
Echoing the sentiment, one viewer penned:" If Natasha doesn't understand that talking about Mikey's performance that way would totally humiliate him then she's got a real problem."
But not all MAFS fans thought that Natasha was completely in the wrong, insisting it was just a joke and Michael had been stirring the pot by telling Mikey.
Meanwhile, doing the radio rounds on Thursday morning, Mikey spoke about his sexual prowess in an interview with Nova's Fitzy and Wippa.

"It wasn't my best performance, I'm not going to lie but every guys been there. I've had some good times, I've had some times that didn't go to plan - I've vomited in bed!" Mikey said.
Mikey also hinted there was more to the incident than what was shown on TV.
"There was a lot more poking of the bear, things that were pretty full on," he said. "Thing they didn't show is that me and Natasha hadn't been getting on. You're only seeing 5 or 10 % of what Michael gets up to, by the end of the show you'll get a better idea of what he's like"
