Men care a lot more about looks than women do. Hence gay men and straight women will invest more into looks. I’m not sure why humans evolved that way but my guess is that it has something to do with healthier women being more likely to carry a baby to full term. With gay men this doesn’t change, it’s just focused on other men rather than women.
Despite what is shown in pop media, gay men still behave more like men than women. They can be way more brutal because it’s more socially acceptable to mock guys looks than women’s. Another point a lot of women fail to realize is that men really are more interested in sex than in relationships when compared to women. Some feminists really protest this fact and make a big fuss but it’s generally the case. Men, like women, have an emotional need for relationships too, but it’s not as strong as a desire when compared to women. It’s not always the case, but it’s a generalization. It’s just that tumblrinas fail to realize that gay men are fundamentally different from them.
