How can I choose which posts to show in my feed?

I’d like to create certain posts that don’t show in my main feed on my homepage.

What I am going to do is keep a main feed that shows up on my home page for certain entertainment topics and then create a separate link to a different part of my site which will contain media files. For that media section, I’m going to create posts, but I don’t want them to show up on my main feed. I need to know how this can be done.

I don’t know if this is needed, but here’s my site:
