There are well-meaning evangelicals who wish to reach out and minister to professing Christians who experience homosexual attraction. This takes different forms. One form promotes reparative therapy. Another form rejects reparable therapy and promotes celibacy. Both forms rightly reject homosexual activity as a live option, since that's diametrically opposed to Christian ethics.
I'd like to take a comparison. Suppose a private jet with a half dozen teenagers, plus the pilot, crashes on a tropical island, killing all but two passengers.
The two survivors are male and female. They make a signal fire, arrange rocks on the sandy beach to spell S.O.S, and patiently wait to be rescued. But after a few months it becomes depressingly clear that no one is looking for them. Although there would have been frantic initial efforts to find them, by that time search-and-rescue efforts have been called off. No one has any idea where the plane went down, and they are presumed dead. Hence, our two teenagers can't count on anyone ever discovering them. They may have to live out their lives on the remote island. Thankfully, it has fresh water, fruit trees, wild pigs, high ground, a cave for shelter, a lagoon for fishing, and a leeward side for protection from squalls and gales. Plus some useful tools from the plane. (That's one of the advantages of fiction. I can ensure a well-equipped island!)
Now, if these were normal teenagers, it doesn't take much imagination to figure out how they'd pass time in-between chores. But here's the catch: let's say the guy is homosexual.
Ordinarily, he'd ignore the girl, but since she's his only human companion, do you really think he'll be remain Platonic? Given the available options, wouldn't he adjust to that situation much like a straight male? Even if that's not his preference–and it's not exactly the girl's first pick–isn't that what he'll fall back on, under the circumstances? After all, he's still designed to have sexual relations with a member of the opposite sex, and find it physically enjoyable. Not only is he perfectly capable of adapting to that role, but he may even take a liking to the girl.
Nowadays, how many homosexual males even give themselves a chance to find out if they have an undeveloped capacity to love a woman? They've been drilled into believing that their condition is immutable, so they jump right into homosexual liaisons. And it probably gels them in that direction.
This doesn't mean the guy in my hypothetical scenario will necessary turn into 100% straight male. I'm not making any predictions.
I'm just making the point that given the male sex drive, I strongly suspect that if a homosexual male found himself in that situation, he'd opt for a sexual relationship with a female rather than a sexless relationship. But how often does that possibility eve occur to homosexuals–especially in a culture that fanatically steers them away from ever considering it. The purpose of my scenario is for someone in that condition to imagine what he'd do in that situation. Take away the male competition. If what's left is a woman of the same age, won't he choose that over nothing? And having done so, he may find there's more to be found in that relationship than he ever expected.
