Someone tell me what this means? Provider has 1 hour-I which i believe might mean "introduction" and she has a 1 hour O which i can only guess means greek.

What is the difference between the 2?

Sounds to me like she's mentioning incall and outcall.  I'd guess that each of those had numbers next to them.

yeh i thought that too but then she has an outcall rate in addition. Maybe she meant that and is being redundant

Incall and outcall. I sometimes see girls advertise both even though the price is the same. I guess they just want you to know that both are available.

And for reference if a girl does introductions she will say "Introductions". No code for that. Sometimes a gal wil offer a special rate for your first session, but I havent seen that advertised in a long time. Not really economical for most escorts. A lot of guys they see are one time only. Also if she has any sense she will NOT keep written records of her clients. So its legally safer but she cant possibly keep track of all the guys she's seen. If you left her alone long enough she may forget about you and charge the special rate again. Good for you but not for her.

And same with greek. If she offers greek she will say so simply. Have not seen any universal code for that yet. Though keep in mind many girls will provide services that arent advertised. It rarely hurts to ask, unless of course she flat out states she wont do certain things and please dont ask about them. If thats the case you dont wanna make her angry by tempting fate.
