If you're like me and punt for girls that are fit as fuck then try and locate ones that work from Edward st area, broad st area or any decent hotels. In my opinion, you can't beat EEs and I don't go over a ton ph.
I find that in these locations, girls generally provide a decent level of service and I do feel a certain level of control of the situation.
Stay clear of touring chicks as they are deluded fucks that are mainly English skanks who have failed to generate a decent level of regulars in their own town IMO.
I never go to houses or smelly flats on the outskirts of the city centre.
