Personally it's not I would like to be a loli as he said, but that I like the depravation of the character. I think I don't identify as much as most people with protagonists from most games, so as I already like corruption games with a female main character, I like the decadence when it's a former guy's spirit falling like that.
It would honestly not be my thing if he was biologically male (I'm personally not into transgenders), but for some reason if the body is "really" female (because magic lol) I have no problem with it. I even find the unique experience rather fun.
I can respect and appreciate that. I enjoy the feeling of immersing myself and identifying with the main protagonist of a game and, of course,
love the complete debasement that comes with it as a result of corruption, hypnosis, or just plain releasing one's inner slut. But then I'm a subby profligate just one bad day away from simply saying 'Fuck it', turning on the brain melter and making myself into a full-blown bimbo (or a cowgirl, because cows are cute and you are lying if you disagree), so y'know... different folks, different strokes.
And that, my friend, is the beauty of unbridled imagination, the kind your homeroom teacher and parents didn't mean for you to find when they said to, "Dream big and follow your heart!"
