Perhaps ask on the porn star board

Maybe some will know her -
and give you a heads up -

( A good heads up lets hope

Most porn stars who escort are either very open about it or totally UTR about it but asking her in the club is generally not a good idea. Remember you are asking a woman if she performs an illegal act...not a good idea. If she escorts and is above board about it she may have reviews or a website that promotes it. Check over on the Porn Star board. Do a search under her name or even post a thread and ask about her.

If she is UTR you are probably out of luck at least for now. Most UTR porn star escorts only see guys on referral form other porn stars or agencies that represent them.

If you have any relationship with some other porn star, she might be able to help you.  She may know if the lady escorts, and she may be able to set up an intro/reference for you.  That worked for me one time.

Just ask her if she does private shows or private dances. Be polite.  She will know what you are talking about and either say yes or no.  If you are polite and respectful you have nothing to worry about.

Get a lap dance. At an appropriate moment, whisper the question in her ear. They've heard it before. Strippers are feeling the recession. It's all about the money for them. If business is slow, they are more agreeable to outside sources of income.

Hey, it works for me!
