Is everyone gay

Answer 1

No.

This sentiment is usually expressed by people who then explain how sexuality is a scale with most people being at least somewhat bisexual. However, even on this scale there are people at either extreme who are purely heterosexual and purely homosexual.

Due to culture, even though most people are naturally in the middle, they shift towards being primarily heterosexual (as much as possible) because it is far more socially accepted. As a result, most open homosexuals are in the extreme homosexual group who are not able to muster any sexual interest in the opposite gender.

Response to above:

This scale is flawed, as it does not take into account asexuality, where a person is not attracted to either sex. It is an oversimplification of what should really be a two-dimensional graph, where the scales are:

same sex: not attracted to - heavily attracted to

opposite sex: not attracted to - heavily attracted to

People start at not attracted to either sex, (which should not be classified as bisexual!), and develop feelings for one or both sexes as they mature. It is genetically natural to develop more feelings for the opposite sex, just as it is natural to develop some feelings for the same sex.
