Yeah, I can't comment on your own experiences or others, only my own. Personally I only seek genuinity (if that is a word), naturally there are preferences and dislikes regarding personalities, but as long as you are your own self, if I can still see your true self even if you wear a social mask at times, thats all it takes for me. 
I dont know if you project your own insecurities onto others by your behaviour, if you do it can be really clear to see and that is offputting - the only advice I can give is to try to let go everything that makes you afraid and just be yourself. As dumb as "be yourself" can sound, strip everything off yourself that isnt "you". Your actual friends dont care how social you are, how energetic or funny you are, they are your friends because they know the real you - be the real you.
