Kinsey scale

1- Predominantly heterosexual, only incidentally homosexual
2- Predominantly heterosexual, but more than incidentally homosexual
3- Equally heterosexual and homosexual
4- Predominantly homosexual, but more than incidentally heterosexual
5- Predominantly homosexual, only incidentally heterosexual
6- Exclusively homosexual
