Interesting research found at EQUAL GROUND is the only organisation in Sri Lanka working towards mainstreaming Lesbian, Gay, Bisexual and Trans (LGBT) issues:
As a risk category, MSM are not limited to small self-identified and visible sub-populations, such as gay men and male sex workers. ‘MSM’ and ‘homosexual’ refer to different social identities. ‘MSM’ refers to the sexual relationships between men, whether or not they identify with same-sex sexual desire. ‘Homosexuality’, however, refers to more than the sexual relationship and may extend to broader relationships with the same sex, i.e. lifestyle, sexuality, etc.
In their assessment of the knowledge about the sexual networks and behaviours of men who have sex with men in Asia, Dowsett, Grierson and McNally observed that using MSM as a category does not always work. From the material they have reviewed there is not any clearly identifiable group of men who can be labelled MSM in any of the countries that they investigated.
“The literature reveals that there are no socially or self-defined groups of men that fit into an overarching category of MSM. What the review shows is that there are just men!! Fishermen, students, factory workers, military recruits, truck drivers, and men who sell sex, and so on: all these categories of men are to be found in the studies and programmes reviewed.”
There was no similar traits in all of the MSM population studied other than them being males, and engaging in sex with other men.
