Although I know they're (probably) joking, all the comments about testosterone and masculinity are kind of shitty. Let's not pull that toxic masculinity crap; someone can be a guy and still be shy and nervous about things. That is, after all, the premise of the manga: you get this attractive, theoretically popular guy with a normal teenage level of horny, but he actually is shy and anxious about someone showing interest in him. That doesn't make him not a guy. It makes him not a stereotype. And it's what this manga is great for doing.
