I think hetero prisoners having gay relationships is the rare exception, not the norm, otherwise it would come up all the time. There are a considerable number of Americans who still think homosexuality is a choice, and they would seize on every opportunity to make their case, just as they used to point to men who, following conversion therapy, declared themselves straight. Problem was, some of those shining examples blew up spectacularly, when they went back to being gay. I remember one of them, a very vocal convert, was caught inside a gay bar (or club), and he wasn't there preaching the joys of conversion. :-) There's a reason why conversion therapy is increasingly banned for minors.
Given how shameful it was to be gay in centuries past, it doesn't surprise me that some married, perhaps had kids, and "dabbled" on the side. I have to wonder, though, how many of them were actually bisexual instead of homosexual. Either way, I'm betting some of their spouses weren't thrilled with the sex life. :) Another common alternative was to move away from home.
I remember hearing (reading?) a quote from a gay activist who said that if straight people want to know what gay people think of straight sex, those straight people should try to picture themselves having gay sex. I may have Connor say something like that, although the scene with Connor's homosexual views in the book are already likely to be too long and need trimming. As usual, he's also trying to piss Satan off. :)
Connor expresses fairly liberal opinions on homosexuality which isn't surprising since he's bisexual. His willingness to push his lover, whom he's grooming as a young leader to gather other young people as converts, to adopt less conservative views is an attempt to cast a wide, inclusive net to appeal to not just gays, who are a small minority of the population, but to the many young people who strongly support gay rights because they consider the bigoted views of older generations incomprehensible.
Christ (Connor) is woke!
One of the details I'm still working through is Satan's reactions to all this. He's repeatedly having to explain away Connor's reckless behavior toward visiting dignitaries, including many Protestants, who come to the Vatican to see for themselves whether Connor is Christ. They make the mistake of asking Connor to show them a miracle once too often. As a result, he chooses a Protestant minister's two sons as volunteers for the demonstration. He offers the sons a drink, which Connor also consumes, containing a relatively minor, short-acting poison.
The sons become sick (Connor doesn't) at which point Connor explains that he poisoned them, but that he's willing to save one of them, whichever their father picks. Connor quotes from the Bible that you should not put the Lord to the test. Fortunately, one of the sons (his future lover) recognizes the words and is able to name the chapter and verse for each instance where words to that effect appear in the Bible. Connor "cures" both sons in response to that and invites his future lover to stay at the Vatican.
Satan has to sit there throughout all this, on the verge of a stroke. :P I may have Connor comment to that effect: "Angelo, you don't look well. Are you having a stroke?"
This version of Connor is so much more fun to write than in book one.
