WHOAH!!! That’s so INCREDIBLY not true, I don’t know where to begin!! First of all, I’ve known plenty of straight men who’re more fem than any woman I’ve ever met. On the flip side, I know of a huge number of gay men who don’t have a single effeminate mannerism. I will be the first to admit that stereotypes exist for a reason, but that doesn’t make them any more than just that; a stereotype. The truth is, you have zero way of knowing whether the person sitting next to you in is straight or gay without them giving you a definive answer or just by looking at them.
