Sex and the City bus tours might be high on the list of places that you wouldn't be caught dead, but desperate men take desperate measures. You might think it counterintuitive to get busy on a crowded bus, but your fellow travellers will be so focused on the cosmos and brunches dancing in their heads, they won't even notice you and your lady in the back getting busy. Your date will appreciate the thoughtfulness of this gesture, as you will help her find out once and for all is she is a Samantha or a Charlotte, if you know what we mean. A word to the wise: before you sign up, be aware that some of these are actually walking tours, which is not ideal for sex.
