thats soo often in yaoi or manga in general its fucking annoying
No, it refers about thinking too much on the other feelings and not acting on it. Typical on manga women stereotypes.
Or it's gone the other direction, suggesting men are impulsive and poor at forethought/thinking through solutions?
That makes sense.
Not all yaoi is by women. there are some who are written by men.
Well it's not just in yaoi manga in movies and everyday life we always hear things like "acting like a teenage girl" or"don't cry like a girl " and many more
Everyone cries and falls in love but it's just more acceptable for girl to be like that than guys so they say it's "like a girl" when in fact it's just "like a human"
