Ah, actually I just want to pay to feel good.
But because I really have no experience with massages
But on the internet or on LINE
everything is described very vaguely

What I want to ask is

Common in gay massages
「OOO」
「B2B oil massage」
「strong-male G-spot massage」
What do they actually mean....
What exactly do they do

If anyone who has had a massage
can tell me in plain language?
Because I have no experience~~ I really don't understand or only have a slight idea ><
