The former Coronation Street actor, who lost out to Ryan Moloney in the public vote, was the second to leave the series after Paula Hamilton.
Asked by Dowling how he felt about his exit, Sam said: "It's been fun but I've had enough."
He added that he was surprised at the crowd's boos as he departed, explaining: "I thought I'd been quite nice."
Quizzed on why he thought Ryan had been picked over him, Sam said the reason was "obvious", explaining that he was "bored most of the time", "not really enjoying it" and "couldn't wait to get out".
Dowling went on to ask why the actor had seemed so tired during his stay, with Sam responding: "It was so much more boring than I thought it would be."
When the evictee was later shown a video montage of Rylan Clark's seeming lust for him, he simply responded: "I love Rylan too."
He picked Lacey Banghard as the person he would like to win, and explained the lack of romance between them by saying that she was "so young and innocent" and that he didn't want to "corrupt" her.
The interview ended with the revelation of Heidi Montag and Spencer Pratt's secret mission, with Sam calling the twist "brilliant" and adding: "This is so much more fun to watch than it is being in there."
