In 2010, Bering touched on similar questions about how to know whether a child will be gay:

In looking carefully at the childhoods of now-gay adults, researchers are finding an intriguing set of early behavioral indicators that homosexuals seem to have in common. And, curiously enough, the age-old homophobic fears of parents seem to have some genuine predictive currency. In their technical writings, researchers in this area simply refer to pint-sized prospective gays and lesbians as “prehomosexual.” This term isn’t perfect—it manages to achieve both an uncomfortable air of biological determinism and clinical interventionism simultaneously. But it is, at least, probably fairly accurate.
