It's been a minute(or a whole lot of minutes) since I've read the comics but I was referring to the films. After 5 movies they could at least let him go to college. I know ASM was a reboot but the constant high school thing is a bit harder to accept in movies as opposed to comic books.
I think that will be something that carries over to the movies though. I'd hope not though. I think if they constantly keep him in his early to mid 20s that could work because I do agree that Peter shouldn't age in the sense of getting gray hair or something like that. If/when Marvel gets him back, I say they should just make him a freshman or sophomore in college and go from there but it wouldn't surprise me if that directive in the comics is the same for the movies breh.
