Sexuality, Gender, Identity, Sexual Orientation and the likes are very broad but interesting topics of human interaction. In order for it to be understood, some experts or people who are very immersed with the systems and concepts underlying this 'whole picture' have initiated some 'metrics' qualifying the rate at which a certain person is interested in sexual intercourse or romantic relationships, and his or her attraction to the same or opposite sex.
Through the years, there have been a deeper understanding of these ideas, especially when more and more have observed that some aspects are yet to be defined and be taken into consideration. There is indeed an evolution.
If you are still confused about how you react sexually and romantically, here's a bit of good history to grasp, and some recent noteworthy claims that are now being fought for as standards to be followed in determining these individuals' mindsets and preferences.
Called the Kinsey scale, it has been the most widely used scale to define how a certain individual is attracted to another person, qualitatively. It is labeled with counts 0-6, zero exhibiting an exclusively heterosexual behavior, while 6 defines an individual with exclusively homosexual behavior.
Whether people are known to be attracted to the same or opposite sex, the thought remains incomplete, since the scale has failed to quantify deeper--in the context of whether the attraction is more of a romantic or sexual one. Meaning, not everyone is into sex and they just wanted to express their love to a person from a certain gender or another.
Langdon Parks responded to the deficiency he identified from the previous cultural scale by establishing a new one. He calls this as the Purple-Red Scale--which has the same '0-6' levels of attraction, but with an additional 'A-F' specification. This A-F leveling is based on how asexual or hypersexual an individual could be.
So, you can be attracted to the same sex, but you are not into his penis or her vagina. Maybe you're just confident to share your life with him or her. Maybe, you're longing for that mother-figure, sister-figure, brother-figure or father-figure that was not given to you when you're still young. Personal speculations aside, this is how this new scale can help you.
Looking at the Alphabetical scale, the 'Aromantic Asexuality' seems very boring and odd, but it does not define the wholeness of the person. Maybe that 'A' person is more of a career individual, changemaker, scientist, or just a plain geek who prefers to interact more with his or her cats, dogs, fish, guinea pigs, or whatever, but not humans. The scale does not intend to degrade these people, same as with those who lies at the opposite end of the scale. Oftentimes, they are the ones who are mostly misunderstood.
On the other end, there are hypersexuals who base their relationship to people on sexual basis. We cannot also blame how their psychological, social and anthropological frameworks were established. It's how they live their lives.
Well, it is of a big help to those people who are very busy with their lives, that they cannot have much time to look for their 'perfect match' in terms of sexual and romantic levels. By not simply saying that you are straight, bisexual or gay, but labels such as B2, C5 and the likes, the longing for sex or romance can be interpreted more precisely.
That's what this scale is worried about, but don't worry about this, this is not the ultimate resort for this matter. Look at Jaden Smith, although these scales are existing, he's not much into these.
