Completely new - what sort of routine is best for me?

I want to try and get a rough balance of focusing length/girth with PE but also want to start somewhat simple and safe.

I don't have the time or environment in which I can be doing things for hours such as extending for long times but with the general impression I get from reading - would it be best to start with pumping and some lighter manuals, 6 days on, 1 off?
