Speaking to Digital Spy at the Monte Carlo Television Festival, Cudlitz explained that he is pleased with the way the show has handled Cooper's sexuality "up to this point".
"I think they need to go there now," he said. "He's a physically fit alpha male - he should be at least trying to date. That's just how life is!"

Cudlitz, who said that he is "extremely grateful" that the show has been renewed, also told UK fans about the upcoming relationship between Cooper and Lucy Liu's character Jessica Tang.
"It's a very, very wonderful relationship that does not end the way you think it's going to," he said. "You realise we've never seen John Cooper physically fit, we've never seen him with another officer who's been a fully fledged officer, and that's a whole different dynamic for John."
Cudlitz also revealed that Cooper will always be "in recovery" though he added that his addictions are "mostly behind him", saying: "He has processed it and is dealing with it, and is dealing with it properly."
Southland airs on TNT in the US and on More4 in the UK.
