This is my experience. Not one error.
As someone else has said, if you use the pull out method, you err on the side of caution. And if you got it wrong, you would apologise profusely, buy condoms and be prepared to shelve sex for a while til the person felt trusting again.
Many of the men on MAFS had barely concealed aggression problems, and seeing them put with vulnerable women was scary. I didn't watch the Australian series after the Dean/Sarah storyline, as I just realised they were pressuring women into having affectionate and sexual contact with men they didn't fancy. There were way worse men than Dean in that show, though, one couple were removed for aggression and I fully believe that there were several relationships that contained coercive control, abuse and (from that association) rape and unwanted sexual contact.
They picked unstable men some of whom looked to be on steroids, or were openly macho and dominant, and just by the DV statistics, were bound to hit on dangerous men- but instead of being on top of this and making it absolutely clear that everything had to be consensual and all even minor situations should be reported to them, having therapists on board with this, they just allowed the 'grey' area to play out til it wasn't grey any more, which is why I stopped watching before this scandal anyway.
