The triangle symbol is widely used as the symbol for asexuality. For most people, asexuality is a mysterious thing to those who aren't asexual and it continues to not be that well understood among sex researchers, which makes sense because sexual health and science comes from many observational studies. Asexuality is by nature the absence of all sexual behavior, making it very hard to study. However a new review of scientific literature on asexuality published in the Journal of Sex Research showed that more sex researchers are paying closer attention to it.
he study highlights include many interesting discoveries. It's important to note that the scientific study of asexuality is barely a decade old. About 1% of the population is estimated to be asexual. The one percent comes from the best available data which stemmed from a national sample of British adults in 2004 from the National Survey of Sexual Attitudes and Lifestyles.
To start off, we need to stress that asexuality is not considered a disorder. Whether or not it should be considered a kind of sexual disorder, similar to hypoactive sexual desire disorder, is something sex researchers have debated. Just because it's rare doesn't mean it's a disorder. The evidence suggests that those who identify as asexual aren't trouble by their sexuality.
The evidence suggests that it's a distinct sexual orientation. Think of other sexual orientations: heterosexuality, homosexuality, bisexuality. In these, sexual attraction is the only way of drawing these distinctions. Through that logic, a lack of sexual attraction should mean that asexuality is a separate, unique category within a sexual orientation framework.
At one time, it was thought that asexual individuals stemmed from a physiological problem when it came to their sexual desire. In fact, asexual people are just as physically capable of erections or vaginal lubrication as anyone else. Their equipment is functional but they feel no actual attraction to anything, as noted by one interview out of the study.
