I think has been one of the better replies to this topic.
In fact, I'm trying to work up the nerve to write a original PWP revolving around two OC's having at it. Its going to be unpublished as its for learning purposes only. In fact, I might have one to three other people read it and have them tell me what they think and how I can improve it.
I don't think I would have the nerve to put it up here at AFF.net I would be too embarrassed until I got it just right.
