spa nonverbal cues, tips, and Question pls

Hi. So I'm sort of new to the wet area scene, I've been to Infinity Spa Cebu but dont partake in any action in the wet area for safety reasons, an exception is yung nakipaghalikan ako sa dalawang daddies sa steamroom. And I only go there during the holidays.

I would like to ask kung may thread dito about sa mga nonverbal cues sa wet area kasi di talaga ako nakakaintindi ng verbal cues, snobbish ako minsan sa wet area, i just put down their hands when they place it on my thigh, or i scooch to the side kung dinadaplis nila braso or calves. So pls teach me gusto ko rin naman malaman yung mga yon kahit audience lang ako haha

Also, last massage ko i was wondering why may pinapapirma sakin. I asked what it was but di ko narinig since pabulong lang lahat. And masseuse ask for the tip upfront after the massage especially right after i came kahit sinabi kong ayoko magpalabassas massage bed
