, but I'm not assuming it will or must happen
Can you name one society that doesn't have some % of it's population that is homosexual, what makes your village special? Granted in societies where they tend to kill or imprison homosexuals, there will be fewer people admitting to it. This is also true in societies that shun them. There are varying numbers on what percentage of the population is gay, but with sixty children in your village if 4% were gay, that would mean at least 2-3 of them probably consider themselves gay. Of course if they are told from birth that being gay is a sin, they will be much less likey to be open about the issue, as they would be shunned for admitting it.
