Make a new profile with a reasonable username. Fill it in with info about yourself. Then come back and act polite and see if things change.
I guess, in the end, it comes down to expectations.
When I read a profile that's basically one sentence and appears to be written in haste, I get the impression that would be the way they would approach any relationship/dynamic/scene....as a one-minute wonder.
I happen to be one of those people who look to see if the person who emails me here has any history on the the message boards and, if so, what it is. The OP's glowing example of forum contribution would most likely be enough for me to barely bother with a response (not to mention, again, the one-track-mind profile).
All of this leads me to believe that the OP, and others with similar history/style, expect instant gratification via a non-whoreish CM slut of his very own simply because he wants one NOW.
Even with a new account/username, this attitude would most likely show itself regardless of the use of polite actions.
Just my opinion, though.
