According to this article and I present it as Exhibit A.
Let that go on record. As stated I will enumerate these four mentioned dudes who OTC strippers.
The User
Ulterior motive is make a transition to any dancer who can support him. Once transitioned he will suck the dancer dry of whatever is possible.
Said dancer never sees the con until it is too late. The alleged dude apparently got the ticket out and is now in another dancers lap.
The Crusader
This reminded of an article written in installment about a dude who vividly tried to walk the straight path while inside the strip club. As articles were furnished in compliance to no agreement, said dude presented himself as observer and also tried to save her from burnout.
Anyway, not that there is a lot say about the Crusader the article clearly defines the character as one who focuses on the imperfections of the dancer, criticizes to certain extent to gain control.
The Married Guy
As mentioned, me having a FG belong to this group as well. And I will use myself here to identify the dude who goes out on a Friday night going to a SC with the intention of executing properly the OTC protocol.
And once the dancer agrees, said dancer is now emotionally and sexually attached.
Midlife Crisis Guy
You can probably pencil yourself here if it matches, there is no harm doing that here as we have something about dancers that we look for.
So yeah, are you tired of the daily grind that it sickens you to a certain point you want to change yourself totally? And by doing this you will get a chance to re-ignite the spark you once had.
Conclusion
Again, there are only four, but I could go on and mention some more.
I do believe these characters exists to a degree and it only needs the right moment and the environment to execute it.
