A faux bisexual is a naive, conforming
girl who pretends to be bisexual because being a bisexual girl is currently considered "cool" in pop culture. It is a trend. Some people refer to faux bisexuals as "trendy bisexuals". The secondary motive for girls pretending to be bisexual is that they believe, due to pop culture, that many or most guys enjoy and are turned on by watching girls engage in bisexual activity.
Many faux bisexuals are so deep into pretending to be bisexual that they actually believe they are, even though they are not.
It seems many people, regardless of their sexual orientation, have a difficult time with the definitions of "bisexual", "homosexual", and "heterosexual".
bisexual: a person who is bisexual is sexually and physically attracted to members of both sexes equally.
homosexual: a person who is attracted to members of their own sex.
heterosexual: a person who is attracted to members of the opposite sex.
example: a girl kissing or even "eating out" another girl DOES NOT make her bisexual. a person's sexuality is all about which gender of person--guys or girls--he or she is attracted to sexually and physically.
KNOWING YOUR SEXUALITY:
Refer to the above definitions. It is all about who you are sexually and physically attracted to.
