I mean, I'm a middle-aged queer man. I am not unfamiliar with this world. And honestly, I'm not saying there's anything wrong with it from either end, as long as everyone is consenting.
I guess I say that because Kyle does, in a fairly chaste manner, sexualize some of his videos. We've seen videos of him working out (badly) and a bunch where he "accidentally" forgets to put a shirt on while editing. He hasn't done that (or a water park video) recently, but given his recent comment about slacking, I'm betting he's not happy with how his body looks.
