i know a guy who wants to pay for my session with a girl.  he lives in nyc and wants to pay using paypal.  this is very curious to me and i was wondering if there are any providers who accept that as payment.   thanks for the help

just ask him to send you a check or cash

Paypal is not a good way to go. For one thing if in any way he sends money - then notifies them you are an adult website provider or xxx industry related payment processor Paypal will freeze the account for 90 days and more than likely refund his charges
Seems crazy I know but this became a huge trend in the last year with men seeking photos phone services fantasy situations etc. Once it was learned how to dance around the system and get something for nothing.
They will make the payment. With paypal however you have 60 days to charge back on those fees. So.. he could see you. Get what he wants and then when you are gone chargeback. You will not have a defense for paypal as you are an adult industry related service that being a no no and there was no real "item" that you can account for delievered. (difference with ebay- they are one company now as of Jan so all auctions paid for are the resp of the buyer and ebay will watchdog transactions to prevent fraud)
The fees that paypal administers for charge backs will be your responsibility and as I said they will most certianly freeze the account.
