Revealing that he's confident that his chosen lady enjoys their, ahem, adult time together, he explains: "I just straight up asked [how it was]."
"I'm not taking notes but making sure that both parties are enjoying themselves."
Well, they say good communication is key, so... snaps for Matt.
But the hottie had even more to say on the sexy subject!
"The best part of a relationship is that [sex] is going to get better as you learn about each other and what you enjoy and don't. It comes with being a good partner."
We've got to wonder if Matt had the same kind of chat with the non-winner he allegedly slept with during filming?
“Matt hits it off with quite a few of the girls, kissing the greatest number of contestants the show has ever seen," an insider recently spilled to New Idea.
"We’re also told that the handsome astrophysicist even beds one of them and it’s not the woman he ends up picking at the final rose ceremony!”
It's not the first time the sext scientist has been questioned as to the intimate details of his life, after reently being forced to reveal he's slept with just seven people.
"How many women do you think you've slept with?" radio shock-jock Kyle Sandilands asked the sexy scientist during a previous interview.
A stunned Matt awkwardly replied, "Funnily enough this is a question on the application form, I'm not sure what the desired answer is either... Rough number... seven."
