"I tended to write like I chat where punctuation is less important than content."
Content is meaningless if your writing is difficult to read and your audience gives up. Your profile is really part resume and part advertisement - it should be as well-crafted as you can make it. In person there are visual and other non-verbal clues that you can pick up on to gauge interest. With a profile you have to be positive, polished and enticing - all with just your writing.
I'd delete the last bit In Looking For - it sounds like you are wanting a lady only so you can get into a club. You also have the same thought in Fantasies and it is expressed better there. The whining about single guys not being welcome is not appealing.
Nobody said this would be easy - good luck!
