I see a lot of this going around but I honestly dont buy it. The ukes from Saezuru Tori wa Habatakanai , Mirai no Kioku, & Honto Yajuu (plenty more where these came from btw) being so well loved while also being fairly slutty (and in Yashiro's case very) pretty much disprove that. It's all about the attitude and the guy here treats the one guy who is nothing but nice to him (sometimes too nice) like gum on the bottom of his shoe. It's all about the attitude. People get mad and they call him slut as a way to vent. But really its his attitude. I'm not saying its right but thats the actual reason. If he didn't sleep around they would find another way to insult him.
people that say they don't like slutty ukes, will they say the same for the seme? what makes them "slutty" anyway, it's not like they are cheating is it?
