I have a fair amount of experience with providers, both incall and outcall, but have only been to a studio (not AMP) once.  I was nervous as a cat.  The young woman who met me in the "lobby" and came back to the room with me was an absoulute stunner and just my type.  Unfortunately, I had some trouble understanding her euphemisms for the level of sex or the cost.  How do I learn the etiquette and the language of this part of the hobby?

The rest of the story goes like this:  I paid her for full service.  She was petite and I am 6'2" and 210 lbs and well endowed.  When she saw me erect she expressed some doubt as to her taking all of me.  She said she was scared of anything longer than her hand  This made me apprehensive of hurting her in the heat of passion, so I couldn't stay up when I was in her.  (Not typically a problem.)  

In the end paid WAY too much for a handjob...!
