There is a lot of work that goes into getting the stories ready for posting. I don't tend to have a lack of ideas, I can always think of a match I'd like to see, women I want to see in action. I've started trying to jot down notes, ideas, or even partial thoughts for future inclusion into stories.
Getting something down, then I can add it into the storylines I'm working on. It might be something for my Catpin stories, or pro wrestling stories, it could be for a one off that might not get written.
Support from others can really help, Kiva has really helped my writing, just talking to others helps generating ideas. Even watching for comments, likes or even the number of views grow and knowing people are at least interested makes a big difference.
However, Real life can put blocks up and just have to be worked through.
