Lately I was really confused for something.
Have you ever thought that Takano san have been an uke when he was with Yokozawa ??

Uke just like he is with Kirishima.

you're definetely wrong. he was the seme. unstable emotions does not equate being uke at all(for example usagi and hiro san) In the novel yokosawa takafumi no bai, it was clearly stated that yokozawa has been touched down there(ass) in their first sex(zenxyokozawa). and takano was his first man..so. .isn't it obvious that yokozawa was the uke? and his attitude in the manga was very ukeish. so that's all.

Well, I don't have a concrete proof. But considering what was Takano's state was at that time, I think he would have done Yoko. And Yoko would have let him because he had feelings for Takano. When Zen and Yoko were having sex, Zen asked something like 'Have you done this before' and I clearly remember there was no comment from Yoko. It just felt like Yoko did was the uke with Takano. And Yoko is a major Tsundere and tsundere tends be usually a uke. I know its a stereotype but I think it fits more that Yoko was the uke.
And I read your earlier comment, that Takano and Yoko only touched each other. But Takano clearly mentioned to Ritsu that he slept with Yoko only once. Does touching each other equate to sleeping together?

Takano says that he slept with Yoko to Ritsu in the anime too. I remember, I guess it was when Takano went on a drive with Ritsu on his birthday. He says that to him on the brigde thingy. Was that a bridge? Don't remember.
I think Yoko would have clearly said that Zen was his first, but he didn't, he hesitated. That I think was an indication that Yoko was a uke. If Yoko was teased down there then he was definitely a uke. Sensei might have kept this issue a mystery on purpose. So we can speculate all we want...right?!! Ah, fuck that, I have always wanted closures. I'm not a fan of open endings.

Takano tells Ritsu that he slept with Yoko when he took Ritsu for a drive on his birthday. He said it wheb they were veiwing the city.
When Zen asked him if he had done this before or something like that, Yoko hestitated. You can have just told him that Zen was his first but he didn't and hesitated and I think that was an indication that Yoko was uke with Takano.
If Yoko has been teased down there before then he must have been a uke with Takano
I think sensei has kept this issue a mystery on purpose. But we are allowed to speculate...right?! Ah, Dammit! I like closures, I'm not a fan of open endings.
SENSEI YOUR SO SMART !!
