I think one of the reasons he was male was just to exemplify how desperate Shinji was for genuine affection - he pretty much fell in love with a man just because he was nice to him. That says quite a lot about Shinji's character.
He started blushing at Kaworu before he even started being nice to him though.
He just thought he was hot, even though he's a guy.
Does bisexuality not exist to you? You guys are retarded. Like >>136038663 says, he was blushing at the very SIGHT of him. This is actually more than he ever did for the girls, in which case he only blushed when they were naked or getting him embarrassed. On top of that, Anno says Kaworu is male because he's Shinji's ideal self. Thus, if he were female, Shinji would have needed to be female too. That's the official statement on the matter. He wasn't male simply to show he was desperate, stop that shit.
Girl Kaworu would have ojou-style long hair
I don't agree myself, but since other anons expressed this sentiment in another thread, I'll post it for them.
He'd make an amazing dandere
She might've been more likeable as a idiot tomboy instead of the generic annoying shounen hero he was.
I wonder how much the medium would change if Ryo Asuka was a girl
Have you not read Devil lady?
>we could've gotten tits in the naked scenes
>ending is no longer gayshit
It was also set up earlier that Shinji doesn't see homosexuality as a normal option for him.
By the time he reaches Kaworu, he's learned that love knows no gender.
Based Kaji was urging Shinji to win the Kaworubowl from the beginning.
That's a pretty accurate description for Manga Shinji.
