Feedback is extremely hard to get online. I suspect (With nothing to go on) that with erotic stories, they get off, close the window, and fix their underwear. Maybe go wash their hands.
Let me put it this way: I've had 2 stories up on Literotica for a decade, and a half, and just recently went back (After a long hiatus.) One of my most popular stories has 160,000 views, and 4.17 stars, out of 5. I just last week got my first comment, on Literotica, after 15 years.
Feedback is nice, but don't expect it.
