She didn't get grossed out when she saw two women kiss?

my friend gets gross out when she see couples kiss man and women. but when we saw a moive with a scene where two girls kiss one another she didnt say "ewww". she trun and look at me (i saw it in the corner of my eye). we are both bi curious but i know she doesnt like me because we are friends but WTF why did she look at me?
