Amazing world of gumball gay

It is heavily implied that Leslie is gay. In "The Mustache", when Gumball became buff, he was amazed by Gumball clenching his butt. In "The Pressure", he and the girls wanted to find boyfriends to kiss, and when they were all confessing to making up their boyfriends, he is heard saying, "Yeah, I made him up too.".

As early as Season 1, & as late as Gumball Chronicles, Leslie has been shown to be gay all throughout the series. Some quotes/actions? Talking about boys with the girls in The Pressure & literally confessing on screen that he made up his boyfriend, I believe his exact quote is “yeah, I made him up too”.
