Editing because now I have more time to do it:

The kind of unspoken theme is that men have dirty sexual impulses and women are pure. So men should avoid "contaminating" women with sex. What are the men here supposed to be protecting women's character against? Their evil penises. Apparently men are so uncontrolled that they need to have posters telling them to keep their zippers shut. Don't besmirch the ladies! It is kind of vague but this just doesn't feel right.
