I know people are entitled to their dating preferences but I can't help but see from reading online and hearing anecdotes that a man being even the tiniest bit feminine is much more detrimental to his potential romantic partners (with both sexes funnily enough), than a woman being masculine.

I always see so many people hate on men wearing makeup, skinny jeans, yoga pants etc... saying "I want to date a real man, not a pansy". Never really hear those from men when they speak about women who have more masculine features (short hair, muscles). Men express their lack of attraction to masculine men, but it seems less extreme than women or gay/bi men expressing their lack of attraction to feminine men.

I've heard this is rooted in toxic masculinity and how being feminine is the worst thing a guy can be.
