FIRST TIMER TRYING OUT SPAS

Hello everyone, I am a shy, 5'6 toned built and discreet 23 M. I want to explore and try some spas around Manila/Makati. Can you recommend spas na hindi ganung nakakaintimidate and let's say "beginner friendly" haha. And paano ba kalakaran sa spas haha, first time ko lang kasi haha.
