The 30-year-old's sex life has been the talk of the social experiment since it first aired in January, and he finally felt ready to take the plunge whilst on honeymoon with his TV bride.
Before sealing the deal, the videographer got off to a rocky start as anxiety got the better of him which resulted in an emergency hospital visit.
Showing his vulnerable side to makeup artist Lauren, Matt told 9Honey he felt an 'emotional connection' he had never experienced with anyone before.
'It sort of just got to a physical point after that, so it was definitely a huge step in our relationship.
It was like, I felt like I had really emotionally connected to someone, and then we just wanted to express that physically,' he told the outlet.
While the fan favourites were not shown having sex on camera, speaking of their first night together Matt revealed it felt 'natural' and was grateful he didn't 'overthink' matters.
On Tuesday night's installment of the Channel 9 staple he told viewers about the milestone, calling it 'a beautiful moment' and 'more than I expected it would be'.
'It was amazing. I think it was worth the 29-year wait.
'Loz is just amazing. We are so close, we are so connected. I just want to be with her - I'm so glad it was with her.'
The feelings are undoubtedly mutual with 31-year-old Lauren adding: 'I'm feeling closer to Matt than ever. The chemistry is back -I can't stop smiling!'
