No one is certain why a majority of individuals are heterosexual and a minority are homosexual, or why some of us accept the sex in which we are born and others do not.

These biological factors set a bias with which the individual meets society to effect sexual orientation and sexual identity. Not everyone, however, sees biology as playing so strong a role.
