>>3113373Shinji isn't around any boys long enough for us to tell.
Kaji is twice his age and Kensuke and Toji aren't considered "attractive" in canon. Just because he didn't show attraction to those three isn't enough proof to say he has no attraction to boys at all.
The fact that he immediately buttered up to Kaworu, a boy, just because of his cute face is enough indication that he's okay with boys, which would make him at least bicurous.
Whereas his interest in women was 98% of the time a flustered reaction to being thrown in a sexual situation.
