Category dependent content

Hello:

I’d like to offer two sets of content for one theme that I’ve developed.

Let’s say I have 2 categories – boys and girls

and I have 2 sections with content – features / examples

if I click features I see a list of posts under the boys’ category (default behavior)

when I click girls, I get the girls’ features posts. if I then click examples I still get the girl pages.

When I click boys, it reverts back to the boy content

What’s the best way to implement this?

Thanks
