You might get a better response if you switch on your Private Messages. Go to User CP (top left of this page) then click on Edit Options (in the left hand column) and then tick Enable Private Messaging in the second box down. Make sure that the next box down (Receive Private Messages only from Buddies and Moderators) is NOT ticked. Finally click Save Changes at the bottom of that page.
Before you proceed with this idea, I think you should look into the Literotica rules re: posting a real-life story about other people, without their consent. I'm assuming that the stories you intend to write are about the boarders you had over the years?
Off the top of my head, I don't know the Literotica policy in this matter, but I can imagine that the rules would require you to exercise a fair bit of creative license in your story, to minimize any similarity to real people and their sexual escapades.
