Within moments of the first reveal on the show, as six women show their legs and private parts on national television, people were asking where all the pubic hair was.
Dom was first up to the plate to have his pick from six women who agreed to show their naked bodies before they showed their faces or had a conversation with him.
Awkward hug on Naked Attraction as Dom picks Tamara
Several people immediately spotted that the women on display kept themselves very smooth, with no hair in sight
As the six panels slid up, there was one thing on common very early on.
And on Twitter, there was a mourning for the lack of pubic hair on display.
Twitter user 'Your Science is Bad' said: 'Did pubic hair go extinct while I wasn't looking?'
Simon asked: 'Where's the pubes? If you don't mind me asking...'
And Tony Bianchi asked: 'What's so bad about pubes?'
The show's first series divided viewers and the first episode of the second series did exactly the same
Jess impressed with her 'brave' tattoo location choice as Dom saw the women naked on the show
He whittled the six contenders down to two, Welsh Tamara and Jess, from Cockermouth
Dom chose to go on a date with Tamara, which surprised presenter Anna Richardson after his exchanges with them both
Dom eventually whittled down the six ladies to two, at which point he too got naked, as it's only fair, and then decided to go on a date with one brave contender, Welsh lass Tamara.
However, viewers then heard later that Jess, who he rejected last, gave him a cheeky follow on Twitter a couple of weeks after filming.
And it seems the longer distance as he lives in Amsterdam wasn't an issue, as the pair began to date.
Dom also met Jess in her hometown of Cockermouth.
Jess was praised by one for getting back in touch with Dom even after he chose the other contestant, Tamara, for a date
During the course of their date, Dom revealed that he's living in Amsterdam, which put Tamara off
But his Naked Attraction experience wasn't over - he heard from Jess a few weeks later and the pair met up a few times afterwards
Izzy was next on the show, and her choices, Isabelle and Eve, noticed that she didn't shave straight away
After Dom's choice came Izzy, a pansexual who dates those who define as men, women or prefer not to define.
Izzy was given a mix of men, women, and two transgender people, one transitioning to a man, and another transitioning to a woman.
But Izzy ended up picking Eve, a woman who chose not to define with a sexual orientation.
When asked why she'd chosen to pick a date on the show, Izzy said: 'It tells you something about who they are if they are willing to get their a*** out on Channel 4.'
Viewers praised the representation of trans bodies as brave Isabelle and Felix showed themselves during the long transition process.
The show has drawn reactions on both ends of the scale, with some praising how open many had become about transitioning, but other being thankful they aren't single
Isabelle told Izzy that her body showed she wasn't afraid to have hair.
When Izzy narrowed her choices down to Isabelle and Eve, she too stripped off, revealing she has chosen not to shave her pubic hair for more than two years.
The programme showed a staggering 363 female genitalia shots and 166 penis shots in its first episode alone.
Last year the show shocked and entertained viewers in equal measure, with thousands complaining about its uncensored content online and media guardians branding it the ‘worst programme ever shown on TV'.

But their date didn't go exactly to plan as Izzy ended up being ill and had to rush off to be sick
The first show of series one featured an average of five penises and two vaginas every minute, with a total of 282 shots of male genitalia and 96 female.
The first episode of series two, which was on at 10pm on Thursday, featured 363 vagina shots and 166 penises - amounting to seven every minute.
Channel 4 said Naked Attraction last year drew an average audience of 1.7 million across five episodes.
A spokesman said: 'In a world where dating is often reduced to swipe left or right this is a light hearted series which aims to demystify the rules of sexual attraction for the Tinder generation.
'In an increasingly complicated dating world, some evolutionary psychologists and sexual scientists believe that our bodies alone may still project the best information for us to select a successful partner.
'Whilst we are socially conditioned not to judge people on their looks, could reversing the dating process and judging someone purely on their naked form actually offer us the best chance of finding a suitable mate?'
