I mean, the thing is that Inoda WAS stated to be quite unhealthy/fat, and even shown this is why bullies were walking all over him before he met KiriSuna. He also had apparently not been eating a proper meal in years, just takeout, until Asuna started making him food, so yeah, is just NTR logic, he shouldn't be able to outfuck all these girls without effort, maybe even less than in FOG, but he can't XD (Also, we know that FOG doesn't work off real stats for anything except apparently fucking ability for some weird reasons, lol)
