Would you like it if male characters were as sexually dominant in shounen series as they are in shoujo?
They are more dominant in shonen than in shoujo.
It may not seem to you that way because you're looking for the obvious signs of dominance. Ignore those.
Focus on who is the center of attention, who manages to get everybody to follow him/her?
Again you are only judging by the obvious standards.
She's the one who's getting blueballed here, while he's running off to his other bitch.
She's dependent of him, so she's advertising herself aggressively, while he can not only freely choose which girl he wants, he can at the same time maintain his "purity".
No, I wouldn't call him alpha, because alpha is used by people who like you only care about certain criteria and not about who's actually in charge.
I'd call him dominant, because that's what he is.

>implying caring about only one bitch isn't beta
>implying alphas can't break a girl's while making her cum at the same time
