No, I wont. Because it's not true. However, if you think that it is not often possible to make a good guess that someone is gay or lesbian based on physical features, then you're at odds with most people who can do so. You can't look at anyone and say they're gay or not, but you can often look at someone and guess that there's a much higher chance than normal. Homosexuality is not a "learned behaviour" as some idiot in this thread claimed. It has a physical basis. To support that I observed that there is often a correlation between physical features and homosexuality. I didn't realize that was controversial.
Relax, it was tongue in cheek. However I know 4 gay people. They all look quite different... 1 of which I never would have guessed was gay... I suppose your statement can hold water, all of them are well groomed (more so than the average man) however this isn't really physical is it? More behavioural? The do all sound similar though.
This is GD, someone will find it controversial

So are you saying quite simply one is either born gay or not? No one could consciously make that decision?
