I have been massaging the attendants for a very long time. To do a proper job and make it more than a "feel up session" is a studied and learned thing.
The girls love it when done well, and once you get good and smoothly effective with the massage method (pressure points, typical sore spots, etc.) , transitioning to a HJ to climax for her is usual and sometimes more for you is the outcome. I find it rewarding.
Being super clean, gentle, respectful and well manicured , having no rough hands or sharp nails is very important.
No matter what you do in the room, personal hygiene is critical, don't forget the breath. Brushing, flossing, tongue scraping, and mouthwash !
Nothing is more of a turnoff or repulsive than someone with foul breath, except maybe, stink ass or rotten pussy !
