As with almost anywhere in the USA, just go onto google and type in Houston Gentlemens Club. You get a bunch. Check out the areas. Anywhere that looks like a posh neighbourhood will be big bucks and/or a waste of time. Find one in the sticks. Then check out the reviews on the boards. Get a taxi there and arrange to be picked up later. Mostly they'll offer BJ or FS in the private dances. BJ usually not expensive.
