What the what? Kleenex for men? Girl-y ear plugs? Boyish sprinkles for boyish cupcakes? WHYYYYYY? From the UnnecessarilyGenderedProducts tumblr:

“Pink and flowers are not the problem! The problem is that the pink and floral designs are inherently coded as feminine (and also usually placed on an inferior version of the base product) and then marketed with sexist, gender binary reinforcing slogans and imagery. Women can buy the “guy” versions if they want, but what about men and non-binary people who like pastel colors and cute things? Things “for men” aren’t looked down upon, but things “for women” are considered embarrassing for a man to enjoy. Just look at the way people talk about “chick flicks” or book series popular with women…

If you like the “for girls” or “for women” products, or things that just happen to be pink, of course you should be able to use them and enjoy them. But there’s a stigma attached to guys liking “female” things. Which is why advertisers will market products like the “It’s not for girls!” candy bar to men who want to reassert their masculinity.
