Man to Man= Gay
Woman to Woman= Lesbian/ Gay
Man to Woman= Straight
It really is that simple, folks.
The problem with the Kinsey Scale is that, it also has its flaws. The Kinsey Scale (Heterosexual-Homosexual Rating Scale) was just an "attempt" by Alfred Kinsey to measure sexual orientation or one's sexual experience. Most even consider the scale as not comprehensive enough to cover all sexual identity issues. The accuracy of the scale is definitely in question.
A person who has or had sexual encounters with the same sex can no longer be labelled as "straight." That's common sense. I don't think Robin Padilla would ever have an "incidental" sex with a man. Ha ha! Why? 'Coz he is that "straight." That simple. Lemme break this down:
According to Alfred Kinsey's chart or scale:
0 is Exclusively heterosexual......Okay, this is self-explanatory.
1 is Predominantly heterosexual, only incidentally homosexual.....Therefore, not straight. The person is only "predominantly" heterosexual, not totally straight.
2 is Predominantly heterosexual, but more than incidentally homosexual....."More than incidentally homosexual" doesn't sound much straight to me.
3 is Equally heterosexual and homosexual......Bi-sexual. Obviously, not straight.
4 is Predominantly homosexual, but more than incidentally heterosexual......"Predominantly homosexual." Self-explanatory
5 is Predominantly homosexual, only incidentally heterosexual......Same as 4.
6 is Exclusively homosexual......GAY!!!
So, what does this tell us? A man can only be identified as either straight or gay. Okay, let's include bi-sexual. If one has or had sex with the same gender, one cannot identify himself/ herself as straight.
