Well how about that, I figured out how to do it without messing anything up.
I was wondering about that, I can usually pick up on if a male is gay by their facial expressions, even subtle ones that heterosexual men usually just don't use. I found an article that may explain the changes that you see, perhaps its related to those different facial expressions exercising certain facial muscles:
..."Gay men do not differ from straight men in the size and shape of any facial feature. Rather, the use of certain expressions can become ingrained in the musculature of the face over time. Since effeminate gay men utilize similar facial expressions as women, they develop female aging and muscle contraction patterns in their face. For example, gay face includes tightness around the mouth from pursing the lips, a facial expression common to gay men and women—but not to heterosexual men. Also, gay men are more emotionally expressive, leading to a general 'tightness' and muscular activation throughout the entire face. Gay face includes an eye expression that is both surprised-looking and predatory. Eyebrows are usually arched higher than that of straight men, and eyebrow hair is manicured. There is often a slightly tan and/or leathery look to the skin, especially among older gay men. Lesbians also have a version of gay face that emulates the facial muscular usage patterns of straight men. They exhibit an underexpression of emotion, relaxed brows, relaxed eyes, and less taut mouth and cheek muscles than straight women. The skin is usually pale and splotchy."
Again, a tad derogatory—but that doesn't mean there isn't some logic there, as well. On the one hand, the "muscular activation hypothesis" seems plausible enough to me...
