MSM and GBMSM
This term "...comprises men who identify as gay, those who are bisexual, and others who would define themselves as heterosexual. The one common element is that, to a greater or lesser degree, they have sex with other men."
The term first appeared in the early 1990s in social research and medical literature during the HIV and AIDS epidemic. It's still used today and some LGBT+ and gay men's health projects use it to reflect inclusiveness. Nevertheless, the term didn't come from the LGBT+ community; rather it's a construct, an invention originating from epidemiologists and professionals to help them in their work.
In 1994, the MESMAC Guide said:
"Men who have sex with men comprises men who identify as gay, those who are bisexual, and others who would define themselves as heterosexual. The one common element is that, to a greater or lesser degree, they have sex with other men.
It should be emphasised that the term does not refer solely to men who do not identify as gay, and some projects and workers have chosen instead to describe their group as gay men and other men who have sex with men. The decision to mention gay men specifically is due to a number of factors.
There is a political element in a conscious decision to use the term gay men stop some fellow professionals have difficulty saying the word gay, preferring homosexual. They may then progress to gays or possibly even gay men. Some workers may feel using men who have sex with men on its own as an all-embracing term encourages the denial of our 'out' gay identity.
Finally, men who identify as gay may not be familiar with the term men who have sex with men and maybe alienated it or mystified by it. It is thus advisable to prefix it with gay men and other ...
It should be stressed that there is a clear rationale behind the use of the term men who have sex with men: reference to gay men alone might leave married men, men unsure of their sexual identity, and others who do not find themselves as gay feeling left out or marginalised. These may be precisely the men that it is important to target, due to their lack of access to gay social and support networks."

Gay and bisexual men and other men who have sex with men (GBMSM)
Most recently, gay and bisexual men and other men who have sex with men (GBMSM) increasingly appears in studies and research papers.
While we understand how the term can be very helpful in sexual health and social research fields, gathering and identifying data, for example, it also diminishes our out gay identity, and some gay men resent being reduced to words and letters. What do you think?
