Dunno about that, the CM girls used to put my hand on their leg, then put a cushion on top.
Then in Vietnam, bars in the afternoon (only customer) I'd sit outside, then they'd take me inside and shut the door.
Then in Cambodia, even in full bars, they'd often put my hand inside their tops, or just take their tops off.
NOTE: I didn't ever touch them, they moved my hands on them.
I don't have much experience of Gogo's, went a couple of times but it didn't do anything for me.
