Agree with Rabbit , you're way over thinking this. The only real thing that might get a little confusing is the gentlemen who don't indulge themselves often and thus, have no usable references. While they aren't newbies, they generally need to stick to seeing newbie friendly ladies as they have no references to give to the ladies that require them as a part of their screening.
Being a newbie has nothing to do with shyness or NCNS. It has nothing to do with worthiness or being molded (unless you're seeing a Domme

). Being a jerk/clingy/erratic and/or acting like a cop/pimp is a red flag no matter how long you've been having fun and the chances of getting a date with a lady plummet. If a newbie is a dick, he's not being turned down because he's a newbie, he's being turned down because he's a dick. 90% of the ladies here won't care about your marital status or your weight. They will, however, care a great deal about your attitude and a lot will be quite pleased with signs of polite intelligence.
Not quite sure what cheating on references is?
We've all been newbies before and 99% of being a newbie is just being aware that you have no idea what your doing, the willingness to apologize for the mistakes you make, and, more importantly, the ability to learn from those mistakes. That and time are pretty much the only ways to crawl out of the newbie hole. I'm really grateful to the newbie friendly girls as not only is seeing newbies risky, it's also a lot of hard work to get them verified. So, when you do finally see your first, be sure to be extra nice to her.
