I believe the simple fact is that if a story was submitted. It is reason enough to submit a review. If you bothered to read it and enjoyed or disliked it.
Think about this.
Obviously the author was looking for a comment or two.
Erotic literature is something of a special type of writing and as such deserves a comment if you enjoyed it or not. I do have a problem with alot of grammer mistakes though. Even though I make alot of them myself. If I submitted a book to a publisher it would of been proofread professionally before submission.
That being said it seems we do have a lot of very gifted authors in this place.
New ones also. I say just keep on keeping on!!!
