I usuallty whine when my stories don't get feedback and when I do people say usual bullshit about "Don't care about people, write for yourself, do what you enjoy most". These words are so overused, it makes such consollation irritating, and almost offensive. Because, of course I've heard that many times.
But it is not just overused. It's wrong.
When you (author) have a good imagination and a particular kinky fantasy, you can do two things.
1. Imagine it for yourself in the bathroom.
2. Want to share it with others. In this case you write a story, draw art or do anything else to flesh your fantasy into some art, that can be shared with others. If you write and publish, you are not doing it "for yourself". You should care about quality and expect, or hope for some appreciation of the audience.
If there is no feedback, it means that you failed. Really. It's much more constructive to critique the weak or dull places in the story, rather than repeat for 1001th time the proverbial write to yourself.
Okay, I'll tell for myself
I was playing in inflation as a child, and played inflation games on paper as a teen. When I learnt programming I started programming them, among other things. One of those games still works for me. I know that when I'm not sure how things will go in bed - all I have to do is play it for five minutes. Twenty five frigging years. No graphics. And it works.
2 Yes, I do have a motivation of sharing it with people, so that they also can fix their issue and move on to other things on day's list - no need to watch porn for hours, save your time!
1 But I also would like to make it look well for me
And I don't know which motivation is the first ^_^
