There are two camps here.
Some people love to post their stories here on the forum. They feel that they get all the exposure they want, and they hope that people will bump their thread enough that they don't have to do it themselves.
Others prefer the Sex Stories site. All my stuff is there, although most of it has also been posted here on the forum. I've had some pieces that have done very well on the Sex Stories site, getting over 100,000 hits and ratings in the mid-90's. Other stories have been hit by toll-voters and have dropped into oblivion quickly.
Try posting your stories both places. On the Sex Stories site, you have the option (before you submit) to choose to allow or disallow comments and to allow or disallow anonymous votes. Here on the forum, all posts are by logged-in members. Of course, there are the socks who will sometimes gang up on you to criticize you if you post something they don't like, but every time they comment, they bump your thread to the top of the page where it's more likely to be seen. Also, most socks slip up sooner or later, allowing others to guess their true identity.
Don't believe everything you read.
