Reserachers said that Gay men who felt sexually unattractive were more likely to engage in risky sexual behaviour.
The new research led by University of Toronto scientists over a dozen of gay men has found that feeling undesirable may lead to psychological and health problems.
"I found that young, white, middle-class men are considered much more sexually desirable than men who are racial minorities, over 40 and poor," said Adam Isaiah Green, Assistant Professor of Sociology at U of T.
The study showed that undesirable gay men face stigmatization, avoidance and outright rejection, which can lead to depression, anxiety and alcohol abuse.
Due to which, they tend to forego safe-sex discussion and, in some cases, condom use, in the context of sex with a more attractive partner.
"We tend to devalue sexual life as something that is extracurricular and frivolous, but this research shows a significant link between sexual desirability and health," said Green.
"Men with low levels of 'erotic capital' are systematically marginalized, which can take a real toll both physically and psychologically," he added.
The study is published in the current edition of the Journal of Health and Social Behaviour.
