Why do straight men have no gaydar? And why do gaymen have this? It seems that we are born with an advanced telepathic ability that astounds from the heterosexual earthlings which completes our sixth sense.
Gaydar (a portmanteau of gay and radar) is the intuitive ability to assess someone’s sexual orientation as homosexual, bisexual, or heterosexual. Gaydar relies almost exclusively on non-verbal clues and LGBT stereotypes. These include (but are not limited to) the sensitivity to social behaviors and mannerisms; for instance, acknowledging flamboyant mannerisms, overtly rejecting traditional gender roles, a person’s occupation and grooming habits.
The detection of sexual orientation by outward appearance or behavior is frequently challenged by situations with gay men who do not act in a stereotypically “gay” fashion, or with metrosexual men (regardless of sexuality) who exhibit a lifestyle, spending habits, and concern for personal appearance supposedly close to the stereotype of fashionable urban gay men.

Let us take things more scientific and proven with research. A genetecist, Charles Wysocki, from University of Pennsylvania’s Monell Chemical Senses Center conducted a survey test, he came up with some interesting results. He asked some volunteers to sniff the underarm sweat from different donors from different genders and sexual orientation. After tallying, it shows a pattern.
It showed that gay men prefers the odor of other gay men. This goes as well with the lesbian. With that on hand, the straigh women rated the odor of straight men commonly higher than that of gay men. This scent-based study enables us, gay people, to pinpoint potential prospects immediately.
Also, at Karolinska University, Sweden, researchers have attested the former finding identifying a particular hormone that is existent to gay people. Adrostenone, a steroid compound that men secrete in their sweat. This excites the brain areas that affect and control sexual behavioral patterns among male homosexuals but it leaves left the brains of straight men unaffected. This hormone affects the scent-driven signals that attracts gay men to each other.
