Since you're still in college, your ability to land pussy (for free) is good.
OTC is for older bachelors, or married guys with some measure of freedom. However, if you're determined to try it:
It takes several club visits to develop the trust with a dancer.
Because of your youth, she'll ask you why you want to go this route (she's used to offers from men, 30 and older).
You must appear ready to take another dancer if she refuses your offer.
You can't appear desperate (younger guys are perceived this way).
Don't give her ANY details about your life. Because of your youth, some dancers will think you a blackmail opportunity, or a joke.
Most important-don't pick a dancer older than you.
With all that said,
In conversation, you ask if she does "private shows". When she asks what you mean, be straight up and tell her, "I'm looking for sex, would you meet me in a hotel?"
If she's a looker, she'll want 300 bucks, but don't pay a penny over that. Negotiate down the price and be firm. Get her cellphone number and verify it (if it's a false number, you got your answer).
Lastly, because of your youth, security is paramount. Don't lose your head if it happens and maintain your security precautions.
