There are, and have been, societies in which same-sex sexual activity has been widespread but has had little or no emotional significance [as with some modern prison homosexuality].
But a preference for, or orientation to, homosexual activity is only part of modern LGB identities.
Some indeed would seek to limit LGB history to a history of sexual activity.
It does not seem accurate, however, to restrict modern understandings of LGB identities to sex.
The central questions raised address the nature and possibility of a "history of homosexuality".
Some scholars assert that "homosexuality" as a discrete identity is a very modern western construction (although the dates suggested by these scholars vary considerably).
Others argue that there have always been "homosexuals" with some self-awareness, but even they would acknowledge that the large, highly visible and open "gay and lesbian community: of the past few decades is a new development in history.
For those who argue that "gays and lesbians" are a new creation, the only "gay and lesbian history" that can really deserve the name is the history of the modern political and social movement.
In the same way the lives and activities of those who were sexually active, or attracted to, members of the same sex, as well as the attitudes of others towards them may fairly be said to constitute a history of interest to modern lesbians, gays and bisexuals.
But what makes up "modern lesbian, gay and bisexual" [hereafter "LGB"] identity?
