I think we all encounter those little demons, more often than we'd like. I'm ridiculously insecure most of the time, and it's only because I'm more stubborn than scared that I even post anything online.
I will say, from the perspective of someone who sweeps this archive weekly and gets to see a great deal of content, you both are marvelous writers. If the dedicated wankers might want more fap-fodder than plot, there's plenty of that here, but I'll take plot and quality over gratuitous smut any day.
