Give me a break. There’s no reason to talk about what happens to men when they see women dressed not tzniusdig.
Tznius is about a women dressing in a way that respects her and her body and this could be taught without mentioning anything about men.
Thousands of girls are educated to be tzniusdig and eidel in dress and manner without mentioning the effects of non-tznius on men.
The point of this mitzvah is not about protecting men because they can see goyishe women barely dressed on the street. It’s about protecting women and that focus of tznius that is succesfully taught in many schools and homes.
Although my daughters are not in 9th/10th grade yet, I know their schools tznius curriculum in high school doesn’t include anything about men and yet the girls in that school as many other schools that stress the importance of tznius without bringing in the men factor, are very tzniusdig and aidel in dress, conduct and speech.
