Create 2 Different Blog Pages

I think this question has been partially answered before, but I can’t find anything that helps with what I am trying to do. I hope you all can help me!

I have 2 post categories – “Teens” and “Adults”
I want to have 2 pages – 1. a Teens page which shows only the posts I have put in the Teens category and 2. an Adults page which shows only the post I put in the Adult category.

I understand how to do this if I was creating top menu items for both the Teen and Adult pages.

However, if I do not want either of these pages to live in the top menu how to do create 2 different pages.

Please help! ??
