I dunno, it seems that the things that make me gravitate toward someone are largely independent of their level of confidence. I like people and have friends who are on both sides of the spectrum and in between (I think? Most of the people I know because I gravitated to them I only know online so it's hard to say). They're probably mostly more confident than I am, but that's just because almost everyone is more confident than I am =p (Idk if I seem relatively confident or even cocky online, that's different, things are a lot easier for me online.)
