Bi people are attracted to both girls and guys. The attraction is romantic as well as sexual. It is a full relationship with deep feelings.
The word bi is from bisexual which is just too long and not nearly as cool, lol.
There are many bi myths like that they cannot be loyal or are confused which is untrue. Being loyal is a choice anybody can make, bi, straight, gay, lesbian, or whatever. And they are not confused, not anymore then anybody else.
There is a difference between bisexual (or bi) and
bi-curious also.
Bi-curious is only being curious about what it would be like to be with somebody of the same sex. Bisexuals are not curious (well not
in that way). They know who they are attracted to.
Grace is a girl and has a girlfriend named
Angelina. She loves Angelina and is only with her. Now if they ever broke up then being that Grace is bi she could either
have another girlfriend or a boyfriend. But her and
Angie are good together.
Even if Grace marries Angelina she doesn't turn into a lesbian, she is still bi.
