Nobody want to "navigate" your website. You can safely remove all those fixed menus. People either came from a social media link, feed link or google search, in which case they have already "navigated" where they wanted, or they found a link in your profile or some other mention of you somewhere, in which case they will come to the front page, where you can put your non-fixed menu, so that they can see at a glance what there is, and use the back button (or click on the logo/title of your page) to get back.
