Not stereotypical ones! Just that I've noticed that many bi people have a little sorta head shake thingy mannerism when they are being attracted to someone I.e. Thinking guy or girl, and when it's the person who likes u, it's sooooo Adorable!!! Anyone agree .....??
According to your observations - many bisexual people - slightly shake their heads - when they notice attractive people? You find the aforementioned behaviour adorable in at least one bisexual person you are attracted to? I personally believe that humans are incredibly varied and that bisexuality is only one trait.
I have seen exactly what you mean in a male friend of mine who is bi (doesn't know i'm bi) who seems to be attracted to me (same for me)! And yes, it's friggin' adorable.
Thank goodness someone gets it!! I seem to do it too and people who like me tend to love it when I do it, and I love it in them, wanna eat them up! Squeeeeeeeeeeee........
