Yeah, and I can understand that, but when the heroes are 16 etc., it looks really weird. And almost all male isekai, romcom and harem MCs basically have the same character. Yeah, honestly, about experience and indecisiveness, that's the age when most people gain that experience. Have you ever seen a gorgeous girl fall in love with an indecisive, powerless virgin? I can admit that it's theoretically possible, but it's never happened everywhere. Also yeah, censorship limits it, on the other hand, a lot of older anime just showed it as something other than hentai, and it was ok. By the way, you mentioned that moment in SAO, was there sex in the manga?
