Separating the boys and girls is so dumb. Like, who do you think you're actually helping by doing this? I guess everyone because they did the whole boy-gets-hard-from-seeing-girl-in-swimsuit thing, proving the point that's being made; It's frustrating.
Like, yeah I get that hormones go a bit crazy at that age, and that it's not far-fetched for someone that age to get hard at awkward moments, being stimulated by small things, but every other chapter does this. Once or twice is fine, now it's obnoxious.
And that's not even going into the horniness being portrayed as a mostly boy-exclusive problem.
