I think that's part of the whole crux of this story that Sou believes the world is surprisingly normal because he happened to be lucky to be surrounded by the women that have most self-control lol. If we remember the news, a lot of women would straight up rape men.
And people hate on Suzuki but, actually, he's a decent guy by the standards of their world. Of course, he's wary of women (for good reason) but he actually has an interest in them and doesn't just see them as beasts like he said other men do.
Yes Suzuki is actually a rather decent guy. Surprisingly so, considering how it all started. But then again he actually goes out and interact with girls while most other boys just stay at home.
As for the rape part... I had a thought. We saw that all the girls in this class are more or less glass cannons when confronted with an actually confident guy.
The whole deal is probably also a cultural thing. Which does not justify it or anything mind you. I'm just saying, probably if a girl gets aggressive, the boy kinda just takes it and does not react in this world.
Similar to how most women are rightly scared in the real world when a guy gets aggressive.
