The stereotype is girls tend to blush more. As the person taking the role of the female in the relationships depicted in all yaoi, the stereotype is he's the girl and he will blush more.
I thought that as I was typing and got angry. Like I think that they think people who take the bottom role are more shameful in a way. Got me mad CassSprinkle
Me too, that's why I like blushy semes like in Mahoroba Days so much
Has anyone else noticed that uke’s blushes are deeper than seme’s a lot of the time?
