Sorry mate, you’re the moron here. After Obergefell v. Hodges, there were lots and lots of people getting married after decades-long relationships. I read about numerous couples that had been together for 40, 50, 60, 70 years, who were FINALLY able to get married.
During the 70’s and 80’s, homosexuals were limited to a constant search of sex outside opposite-sex relationships. That is what has been well documented, dingbat. If you’re not allowed to have an open gay relationship, you might have to make do with short encounters with strangers, but that was probably not what most of them actually desired.
If you want documented constant search for sex outside of a relationship, check out the US President. If he can stay married to Melania two more years, it will be the longest of his three marriages.
