Can't be compared like that. All depends on the girl actually.
For GL, fuck is guaranteed but sometimes the session is quite rushed - especially the 20 or 30 min session - like a very surreal experience or a dream (nightmare?
) You wondered what you paid for, sometimes.
For massage, though it's just a HJ, some girls are so good at milking your dick, it honestly can feel more satisfying than a FJ. And you get a massage too.
That being said i have managed to get good massage and FJ from GL cat 40 thai WL ... by booking 2 sessions. So it all depends.
