Thailand is gr8 if you want to fuck whores. In fact, there's simply nothing else like it on the planet - just to remind everyone that Thailand's crown jewel, Bangkok, has fucking NANA PLAZA as an OFFICIAL ATTRACTION, a multifloor complex of literally nothing besides go-go bars and by the hour fuck rooms.
As for geomaxxing there, I agree its kind of a cliche at this point, and you should all be a little more adventurous.
