The Practice of LGBT
There was SSM all throughout history.
In terms of Jewish history, we only find one case of attempted SSM rape, in the story of Levite's Concubine (Pilegesh Bagivah, Judges 19). Otherwise there is not much in this space at all, both in recorded events and Torah literature addressing the issue. There was no need to deal with it like there is these days.
Was the Practice Allowed?
SSM was generally allowed in ancient cultures. Egypt, Greek, and Roman empires have this practice recorded. The context in all these cultures has been that of general promiscuity, as opposed to official marriage.
However, with the popularization of Monotheism (Abrahamic religions) around the world, SSM became intolerable and punishable. This extended to ill treatment of LGBT themselves, regardless of whether SSM was committed or not.
The Modernity Age had introduced the following forces into western culture. These have been kinder and more inviting toward LGBT, SSM and its legalization:
Secularization – undermining those religious doctrines against LGBT
Liberalism – affording freedom to the individual to conduct himself/herself in whatever manner he/she chooses. Obviously without interfering with that same right of others, but with undefined (or no) moral standards.
Materialism – the pursuit of physical pleasures becoming the goal of life.
Indeed, the tables have eventually turned to the extent of Pride and the intolerance of opposition to SSM, prevalent today.
Ironically, the advance of science has seen the development of correction treatments of LGBT. Starting in the late 19th Century, different methods have been offered but with varying success / failure rates.
Was the Practice Institutionalized?
Even when widely practiced in the past, SSM was never officially recognized as proper marriage until recent times. In the last few decades, country after country in the western world has recognized and legalized SSM (to varying extents in terms of rights afforded).
The only historical exception to the above is the Generation of Noah's Flood, around 2200 BCE, when SSM had become legal.
More about that generation later on.

Not much Jewish history / literature. To the extent it gets the smallest mention by Maimonides in his all-encompassing work of Jewish Law, and no mention in the Code of Jewish Law (which focuses on practical laws).
SSM common in Egypt. "מעשה ארץ מצרים / The Deeds of Egypt" Leviticus 18:3 and Torat Kohanim & Rashi on this verse.
SSM institutionalized before Noach's Flood. Bereshit Rabba 26:9.
SSM only institutionalized before Noach's Flood. Ref Talmud Chulin 92b. Sodom had not institutionalized SSM as in marriage of couples but as raping of guests (Bereshit Rabba 50:10).
