t. gay

Yes, there are ways to tell but it can be very subtle. I'm closeted and no one has ever thought I'm gay (I suppose I should mention I'm from a rather conservative christian country, thus the memeflag. if's not outlawed obviously, but still 'taboo'). The most obvious sign are personality traits. And personality traits are the most well-documented, undeniable evidence that there are differences in the brain anatomy of heterosexual and homosexual men, from a meta analysis of more than 200k people. Homosexual men have spatial reasoning similar to that of heterosexual women. I'm sure there are ways to approximate someone's spatial reasoning without a test. And that, combined with the index finger, FWHR (which is proxy for testosterone levels, assertivenes, dominance and masculinity) and maybe some other traits, an experienced person might be able to tell if someone's homosexual with a great accuracy. It would require training, certain personality traits and maybe EQ as well as IQ. And this is demonstrated by the fact that AI could tell homosexuals at a high rate
